- Measurement of relative humidity, air temperature and barometric air pressure
- High accuracy
- Long-term robustness
- Sintered filter cap
- Stainless steel housing
Hygro-Thermo-Baro transmitters COMPACT are designed to measure relative humidity, air temperature and barometric air pressure.
PTH Thies Compact – Meteo 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:
- high long-term stability,
- virtually linear characteristic,
- good dynamic behaviour,
- dewing resistance,
- low temperature coefficients,
- small hysteresis.
