The Tramex FBSK is a compact kit designed for professionals who depend on accurate, reliable live and logged readings of relative humidity, temperature, dew point and humidity ratio. It monitors both ambient and in-situ conditions in buildings and building materials such as concrete as per ASTM F2170.

The Tramex Feedback Datalogger and Tramex Meters App log up to 100,000 data point entries, transmitted wirelessly via Bluetooth BLE technology to your mobile device. On the app you can visualise live readings, thermal conditions and psychrometric charts, as well as create and export spreadsheets, charts and reports. The Feedback Datalogger requires the Tramex Meters App and a compatible iOS or Android mobile device. The kit comes in a protective Tramex Easy-travel case.
