FLOORING & WOOD PRODUCTS:

Why should i use a Moisture Meter

Structurally sound and beautiful in appearance, wood is the ideal raw material. Flooring professionals know that Moisture content is the single most important factor affecting the quality of a wood flooring installation.

To ensure quality from the manufacturer to the final installation, Delmhorst offers a full range of Moisture Meters that help minimize defects such as shrinkage, cracks, and splits. Years of experience, high-tech tools and controls, and premium grade wood cannot make a difference if Moisture content goes unchecked.

How does a Moisture Meter work

There are two types of Moisture Meters typically used in the flooring industry. Pin-type Meters, which utilize the principle of electrical resistance, use wood or other hygroscopic materials as an element in a circuit by driving two pins or electrodes into it.

Pinless Meters use radio frequency signals to penetrate the material being tested. There is no pin intrusion into the surface of the material you are checking.

Which type of Moisture Meter works best for a flooring job

To quickly identify wet areas in floors, pinless Meters are easy to use. They offer the convenience of testing a large area quickly, and help you determine if further testing is required in certain spots. A pinless Meter may also be used to determine if water-born finishes are dry and ready for a second application.

A pin type Meter, on the other hand, is the best way to identify the exact location of Moisture in sub-floors. The key to finding hidden Moisture is to use an electrode with insulated contact pins. These pins read only at their un-insulated pin tips, allowing the contractor to drive the pins into the floor and through to the sub-floor, noting readings at each level of penetration.

What are the ideal Moisture conditions for the sub-floor and wood flooring so problems can be avoided

Flooring strips or planks - and the sub-floor - should be brought to equilibrium before installation. Best results are obtained when the wood sub-floor is within 4% MC of the flooring, maximum.

If the floor is on concrete, especially a slab on grade, the challenge is to be sure that the slab is dry and not likely to pick up Moisture later on. Please refer to the Operating Instructions section under PRODUCT SUPPORT for more info.

Why doesn't the Meter give Moisture content in percent on concrete

Because the exact makeup of concrete is usually unknown, it is virtually impossible to provide a %MC calibration. Delmhorst Moisture Meters feature a 0-100 reference scale that provides dry to wet indications of the presence of Moisture. Factors that affect concrete Moisture readings include it's mix ratio and type, voids, and depth that the pin penetrates.

How does static electricity affect Meter readings

In cold and/or dry climates, static charges may cause erratic Meter readings in the range below 8 percent. Measuring such high resistance under these conditions is difficult enough, but the winter months can make it more so. The analog Meter pointer "jumps" all over the scale or the digital display may flash erratic numbers. To minimize the effect of static:

  • Try not to let the electrode cable dangle.
  • Drive the electrode pins into the wood with the Meter turned off, and then turn the Meter on when you are ready to take the reading.
  • After driving the pins, place your hands next to them on each side of the electrode to help discharge the static from the board.
  • You can also try passing a damp cloth over the board's surface to pick up any static charges before driving the pins.

These suggestions are not guaranteed. However, depending on the conditions, any one of them can work, either alone or in combination with another.

Are there board width limitations in using Moisture Meters

Board width is not a limiting factor when using a pin type Moisture Meter. As long as the pins make good contact, the Meter can be used on anything from small dowels to wide planks.

For accurate results with a pinless Meter, the material you're testing must be at least the width of the scanning area on the bottom of the Meter. Otherwise the Meter will not make firm contact with the board and may provide inconsistent, unreliable readings.

How Do Delmhorst Meters Handle Readings on Rough-Surfaced Lumber and Cupped Boards

With a pin-type Meter, these conditions are not a problem. Just drive the pins as you would normally, insuring firm, positive contact and detect unknown gradients.

Pinless Meters, however, need firm contact to a flat surface so their readings on uneven surfaces may be unreliable.

How do i determine if the Moisture problem is in the finished floor or the sub floor

In order to find this out, you must use a pin type Meter with insulated contact pins. First, take several readings in the layer just below the surface; then make a series of core readings, closer to the center of the board thickness. After you have noted these readings, hammer the pins through the flooring material until you make contact with the sub floor.

If your readings throughout this process are uniform, then there is not a Moisture problem. If readings increase as you go further into the floor, and again in the sub floor, this indicates that the sub floor is a source of Moisture.

How does temperature affect the accuracy of Meter readings

After Moisture content and a Moisture gradient, if one exists, wood temperature is the most important factor affecting the accuracy of your readings. As wood temperature increases its electrical resistance decreases and indicated Moisture content rises. The lower the temperature, the lower the indicated Moisture content. Depending on the temperature and Moisture content, you may have to make a correction.

Does the glue used in plywood affect Meter accuracy

In most cases, no. To verify this, use insulated pin to make individual tests by touching the outer ply, glue lines, and center plys. If the glue reads the same as wood, use the Meter on plywood as you would any solid material and take the readings at face value, without species correction.

How Do I Keep a Delmhorst Meter in Good Working Condition

Delmhorst moisture meters are well known for their ruggedness and ability to withstand years of rough handling. Like any testing instrument, a little care goes a long way toward trouble-free service:

  • Store the meter in clean, dry place
  • Change batteries and pins as needed
  • Keep the meter and electrode clean by using any biodegradable cleanser sparingly on external parts only.

If you have any further questions on using a moisture meter for flooring applications

WOODWORKING, INDUSTRIAL & MILL:

Why should i use a moisture meter

Structurally sound and beautiful in appearance, wood is the ideal raw material. Delmhorst customers in the woodworking/lumber industry know that moisture content is the single most important factor affecting the quality of their products.

To ensure quality, from the mill and dry kiln to the finishing floor, Delmhorst moisture meters help minimize defects such as shrinkage, cracks, and splits. Years of experience, high-tech tools and controls, and premium grade lumber cannot make a difference if moisture content goes unchecked.

Are there different types of moisture meters

There are two types of moisture meters commonly used in lumber and woodworking applications.

A pin-type uses two pins that penetrate into wood at the users desired depth. Pin-type meters are the only instruments that indicate the moisture conditions inside a board or a piece of wood. Using insulated pins, only the uncoated tips are exposed to the wood fiber, providing more accurate readings of moisture content at various levels of penetration. Using a pin type meter with insulated pins is still the most effective method to determine moisture gradient, which is the difference between shell and core moisture content.

Pinless moisture meters read moisture closest to the source of the magnetic field, in this case, at the surface. For quickly scanning finished product, a pin-less meter is a convenient way to identify a problem area. However, a pinless meter cannot differentiate between shell and core moisture content and will not detect a moisture gradient. Also, readings provided by a pinless meters are affected by surface moisture.

Please refer to the diagram below for a basic look at the difference between readings obtained from a pin-type meter compared to a surface meter.

This diagram illustrates that pin-type meters and surface meters provide different information about the moisture content in a board. Each technology may be appropriate for different applications. Before choosing a meter, it is important to understand these differences in readings and choose the type of meter best suited for your particular application.

How does a moisture meter work

Using the principle of electrical resistance, pin-type meters use the board as an element in a circuit by driving two pins or electrodes into it. This method works because moisture conducts electricity well and dry wood is an effective insulator.

Most pinless meters use the capacitance method, which uses the relationship between the moisture content and the dielectric properties of the wood.

Both the resistance and the dielectric properties of wood change in direct proportion to its moisture content, within a specific range.

In what range of moisture content do pin-type meters operate

Resistance-type meters express moisture content as a percentage of the oven-dry weight of the wood. These meters work best from the range of fiber saturation point (25 to 30 percent) down to around 6 percent. Below 6 percent, it's tough to make accurate, repeatable readings because of the high electrical resistance in really dry wood. This is particulary true at low relative humidity levels, generally below 30 percent.

Electrical accuracy of all Delmhorst meters is better than 0.5 percent between 6 and 12 percent moisture content; better than 1 percent between 12 and 20 percent moisture content; and better than 2 percent between 20 and 30 percent, or at fiber saturation point. You can check accuracy either through the internal check or with a Moisture Content Standard.

At what moisture content level do i minimize defects

Acceptable moisture content depends on the final use of the wood. Wood for fine furniture should be dried to 6 to 8 percent in most areas of the country, with very little variation among pieces and between the shell and core.

Appropriate moisture content is also climate-driven. To determine the attainable moisture content - or equilibrium moisture content (EMC) - in your part of the country, hang small, thin samples of a wood species in your shop or plant and taking daily readings. When the samples' moisture content remains constant, they have reached the equilibrium level. This level will change from season to season, but you'll know the range within which to work. (Figure III)

How do i determine the distribution of moisture in a board

Here's where Delmhorst recommends the use of a pin-type moisture meter.

First, to determine how the moisture is moving through a board, make a series of shell readings in the layer just below the surface; then make a series of core readings, closer to the center of the board thickness. The Delmhorst 26-ES electrode with insulated pins is the easiest and surest way to detect a moisture gradient.

Since the 26-E pinpoints are not insulated, two or three quick readings at different levels of penetration will indicate if the board is well seasoned, or properly dried. A normal gradient usually develops from the wetter core to the drier surface, with an average reading at between 1/4 to 1/5 of the board thickness. Even non-insulated pins, which measure the wettest fibers, will provide a good indication of how the wood is drying.

If you are using non-insulated pins, push the pins just about 1/16" into the surface, read the meter, and then push the pins to their full depth. For kiln-dried stock, the final reading should be between 6 and 12 percent; with your first reading about 1 percent lower. For air-dried stock, the final reading is typically between 12 and 19 percent, with the first reading between 2 and 3 percent lower. Meter readings outside of these ranges indicate that the board is poorly seasoned.

Pin-less meters scan through the cross section of a board taking into account the moisture in the entire penetrated area. If there is a high concentration of moisture at the surface, the reading will be skewed to reflect this surface moisture. If the surface is dry and core moisture exists, the readings will be lower than the representative moisture levels throughout the board.

Does surface moisture skew a delmhorst meter reading

Moisture caused by exposure to rain, fog or high relative humidity is easily and accurately detected with insulated pins.

If you're using non-insulated pins, push them 1/16" into the wood and read the meter. Then push them to their full penetration. The meter reading should increase by 1 to 2 points, just because of the greater contact. If there is no increase, or the increase is less than 1 percent, the wood is wet on the surface and the readings are unreliable.

As described in the answer to the question above, readings taken with a surface meter are affected by surface moisture, making it difficult to determine if the surface moisture is a result of standing water caused by rain, or if it is representative of the moisture content throughout the board.

How many measurements does delmhorst recommend for an accurate sampling

Accuracy of the readings depends on how representative the samples are of the entire load. In an ideal situation, when all the boards in a load have the same moisture content, and the distribution in each board is uniform, only a few readings are needed.

But since this ideal condition doesn't often happen, start by checking a large percentage of pieces. If the readings are within close range, it's apparent that the load is fairly uniform. For critical use, check 5 or 10 percent of the load, and be sure to look at boards from all parts of the load. Check slower drying quarter sawn boards as well as flat sawn lumber. If you can only drive pins into the edge, be sure to use the longest pins available to reach the fibers as deep as the board is thick.

The Delmhorst RDM series moisture meters with data collection and statistical analysis capabilities are ideal for simplifying the entire sampling procedure and providing backup documentation.

How far should i drive non-insulated pins into wood

To full depth if possible. However, at moisture levels below 10%, it is usually sufficient to make good, positive contact with the wood. At higher levels of moisture and especially if you have a steep gradient, full penetration is a must. Otherwise you can have discrepancies between meter readings and actual moisture content of as much as 5 or 6 points, especially in the range above 20 percent. For best results in such cases, use insulated pins.

Do i get the same reading if i use 2-pin insulated or 4-pin non-insulated electrodes

The original Delmhorst calibration was developed with a 4-pin electrode - four non-insulated steel needles, with 5/16" penetration - in samples with uniform moisture distribution. For greatest accuracy, a small correction is necessary when using electrodes with two insulated pins. The latest Delmhorst models available are calibrated either for the 2-pin electrode only, or are programmable for both 2-pin and 4-pin electrodes.

How does temperature affect the accuracy of meter readings

After moisture content and a moisture gradient, if one exists, wood temperature is the most important factor affecting the accuracy of your readings. As wood temperature increases its electrical resistance decreases and indicated moisture content rises. The lower the temperature, the lower the indicated moisture content. Depending on the temperature and moisture content, you may have to make a correction.

Delmhorst meters are calibrated at 70 F (20 C). In field use, no correction is necessary if the wood temperature is between 50 F and 90 F. If the temperature correction is not built in the meter, use the slide rule or chart we supply with each meter.

The temperature of the wood does not affect pin-less type meters, unless the lumber is frozen.

Are delmhorst meters accurate on frozen lumber

As long as the wood is not frozen solid and remains conductive, a pin-type meter will give reliable readings. However, most instrumentation, unless specifically designed for extreme weather conditions, will not work well in constant sub-freezing temperatures.

How do delmhorst meters correct for species variation

When using a pin-type meter, all species yield different readings at the same moisture content. This is due to the fact that the electrical characteristics of different wood species vary. Delmhorst uses the USDA standard - Douglas Fir - as the basis for all calibrations.

When using a Delmhorst meter on other species, either refer to the species correction chart, or key in your species into one of our microprocessor-based meters for an automatic correction.

Pinless meters also yield different readings for different species. However, instead of electrical characteristics affecting the readings, wood density affects the readings. Refer to the species correction chart enclosed with your meter to adjust the readings accordingly.

Does a group species correction provide an accurate meter reading

Species corrections are most accurate when handled as an individual correction, either through the a species correction chart, or automatically, through software. While not as accurate as individual corrections, the group correction is adequate for practical purposes, as long as the correction is close to the individual factor for the species.

What about exotic species or other species not on the charts

If the species correction is simply not available, you can take readings below 10 percent at face value. Any correction is so small that depending on the application; a correction may not be necessary.

A good moisture meter is still valuable, even without a correction factor because you can use it to determine the equilibrium moisture content (EMC). A meter reading by itself is not always as important as allowing the wood to attain its EMC level where it won't change dimension, crack, or split.

Does the glue used in plywood affect meter accuracy

In most cases, no. To verify this, use insulated pins to make individual tests by touching the outer ply, glue lines, and center plys. If the glue reads the same as wood, use the meter on plywood as you would any solid material and take the readings at face value, without species correction.

What about the chemicals in treated lumber

Recent studies have shown that you can use a Delmhorst meter with confidence at the treating plant, job site, or when the wood is in service if the preservative is a "C oxide" formulation (CCA-C) widely used today. Our experience has shown that at higher moisture content levels (above 20 percent), chemically treated lumber tends to yield somewhat erratic readings.

What about particleboard and other manufactured materials

Chemical additives may or may not affect meter readings. Use the meter to make qualitative, comparative readings. If greater accuracy is required, Delmhorst can help you to develop a specific calibration.

How do delmhorst meters handle readings on rough-surfaced lumber and cupped boards

With a pin-type meter, these conditions are not a problem. Just drive the pins as you would normally, insuring firm, positive contact and detect unknown gradients. Pin-less meters, however, need full exposure to a flat surface so their readings on some uneven surfaces may be unreliable.

Are there board width limitations in using moisture meters

Board width is not a limiting factor when using a pin type moisture meter. As long as the pins make good contact, the meter can be used on anything from small dowels to wide planks.

For accurate results with a pinless meter, the material you're testing must be at least the width of the scanning area on the bottom of the meter.

What happens if i bring a delmhorst meter into a dry kiln

Moisture meters, like most precision instruments, are sensitive to moisture. We do not recommend taking a meter into a kiln, especially from cold surroundings. If you must, take a few minutes to warm up the meter and electrode to a maximum 100F, so that the higher temperature and moisture levels in the kiln will not affect the meter for a few minutes. If you don't acclimate the meter, readings will be erratic at best.

While Delmhorst meters are built for the harsh mill environment, continued exposure to high heat and humidity will invite corrosion and shorten the life of a meter's keypad, display and PC board components.

How can i monitor moisture content during drying without going into the kiln

Use the Delmhorst Kil-Mo-Trol, a remote probe system that measures the moisture content of lumber during the drying process. Resistance probes or contact pins are located at various "stations" throughout the lumber packages to monitor shell and core or core only moisture content readings. This technique is proven for both hardwood and softwood drying, and can be used in any type of dry kiln, pre-dryer, or air-drying operation. For more information about Kil-Mo-Trol, please close this window and click on the Kil-Mo-Trol Moisture Monitor button.

How does static electricity affect meter readings

In cold and/or dry climates, static charges may cause erratic meter readings in the range below 8 percent. Measuring such high resistance under these conditions is difficult enough, but the winter months can make it more so. The analog meter pointer "jumps" all over the scale or the digital display may flash erratic numbers. To minimize the effect of static:

  • Try not to let the electrode cable dangle.
  • Drive the electrode pins into the wood with the meter turned off, and then turn the meter on when you are ready to take the reading.
  • After driving the pins, place your hands next to them on each side of the electrode to help discharge the static from the board.
  • You can also try passing a damp cloth over the board's surface to pick up any static charges before driving the pins.

Depending on the conditions, any one of them can work, either alone or in combination with another.

Why do meter readings not always agree

If two meters are not of the same manufacturer, readings will likely not correspond, because of the different calibrations used. Made in the USA, Delmhorst meters are calibrated on the USDA standard, while foreign made meters use other standards and often have different species and temperature correction factors.

Even readings on two meters of the same manufacturer may vary. Assuming both meters are electrically correct, the difference usually can be attributed to use of different electrodes, pin penetration, and species and temperature corrections. When meters are used for lumber inspections by vendors and buyers, the two parties should have a basis for comparing readings obtained with the instruments they are using.

How do i keep a delmhorst meter in good working condition

Delmhorst moisture meters are well known for their ruggedness and ability to withstand years of rough handling. Like any testing instrument, a little care goes a long way toward trouble-free service:

  • Store the meter in clean, dry place
  • Change batteries and pins as needed
  • Keep the meter and electrode clean by using any biodegradable cleanser sparingly on external parts only.

If you have any doubt about the working condition of your meter, send it to Delmhorst. We can repair and re-calibrate your instrument to its original standards and return it to you quickly.
