Hygro-Thermo-Baro transmitters COMPACT are designed to measure relative humidity, air temperature and barometric air pressure.
This sensor is intended for use at meteorological measuring stations for connection to datalogger systems. Thanks to its universal interface the sensor can also be used as a single solution in every application suitable.
The use of high-quality sensors for the parameters to be measured allows the sensor to achieve the following:
