The Tramex FBSK5.1 Feedback Datalogger Starter Kit has been designed and developed by Tramex for professionals who depend on accurate, reliable readings using the very best, state of the art technology and performing ASTM F2170. The Feedback DataLogger and App log up to 100,000 data point entries for relative humidity, temperature, dew point and grains per pound, transmitted wirelessly via Bluetooth BLE technology to your mobile device. On the App you can visualize Live Readings, Thermal Conditions and Psychrometric Charts, as well as creating and exporting spreadsheets, charts and reports. The Tramex Feedback DataLogger requires the Tramex Feedback Data Logger App and a compatible iOS or Android mobile device.
With built-in Ambient RH + Temperature sensor; Plug-in RH + Temperature Sensor (optional); Contact Temperature Probe (optional) providing the best available accuracy tolerances of 1.5%RH & 0.1F.
