RFTF
Active room humidity and temperature sensor optionally with passive sensor
Application
The RFTF is a humidity/temperature sensor for recording the relative humidity and temperature of the air, e.g. in refrigeration, air-conditioning and clean-room applications technology, in living spaces, offices, hotels, technical rooms, meeting and conference venues.
