Description

the industrial sensor

The HygroFlex8 provides you with trouble-free, accurate moisture measurement results through the most stable sensor available in the market. This transmitter is designed to reduce maintenance time to a minimum.

Scheduled calibrations can be carried out in seconds – while the device continues to measure – using a calibrated sensor. This ensures even greater accuracy. HygroFlex8 transmitters are extremely reliable and functional in measuring relative humidity and temperature (0.8 %RH < 0.1 °C accuracy)
