Features

• Digital, non-destructive moisture meter.
• Deep signal penetration to over 25mm (1") into the materials being tested without the need to damage the surface. Signal penetration depends on material being tested and meter setting.
• Specific gravity adjustment for wood species.
• External Rubber electrodes make direct contact with the material being tested for best sensitivity and repeatability.
• Wide range of readings for wood of 5% to 30% and 0 to 100 comparative for all other materials.
• Backlit, large, clear, easy to read LCD display.
• Hold function enables user to "freeze" the reading. Useful for taking readings when the meter face is not visible.
• Switchable "On" or "Off" audio warning tone.
• Automatic power cutoff switches "Off" when not in use.
• Automatic default to last user setting when switched back on.
• Battery operated (included).
• Attaches to plug-in wood probe (optional).
• Attaches to plug-in Tramex Hygro-i2 relative humidity probe for relative humidity, temperature, dew point and mixing ratio readings (optional).

Desing

The Tramex MRH III Moisture and Humidity Meteroperates on the principal of non-destructive impedance measurement. Co-planar electrodes are fitted on the base of the instrument from which low frequency signals are transmitted into the material under test, measuring the change in impedance caused by the presence of moisture. This reading is translated by the instrument into a moisture content reading.

Hygrometer mode:

When the Tramex Hygro-i2 Relative Humidity Probe is plugged into the Tramex MRH III Moisture and Humidity Meter, it automatically changes to Hygrometer Mode. The Tramex Hygro-i2 Relative Humidity Probe provides the ideal solution for measurements of ambient relative humidity, temperature and dew point conditions within the building structure and in structural materials such as concrete flooring, walls etc.
