Feedback Data Loggers

Temperature and Relative Humidity Measurement

The Feedback DataLogger and App have been designed and developed for professionals who depend on accurate, reliable readings using the very best, state of the art technology.

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 Feedback DataLogger requires the Tramex Feedback Data Logger App and a compatible iOS or Android mobile device.
