Humidity transmitter Rotronic HygroFlex HF3 with improved accuracy

hygroflex3

Based on our standard factory calibration, the accuracy of wall and duct versions of the HF3 industrial transmitter can now be classified with improved accuracy. The HF3 accuracy is now ±1.5 %rh and ±0.2 K (previously reported ±2 %rh and ±0.3 K). All product documentation has been adapted accordingly.

The HygroFlex3 humidity and temperature transmitters with fixed probe are based on the Rotronic-IN1 sensor with high long-term stability. They are ideal for monitoring ambient conditions in a wide range of applications. The HF3 series is part of the extensive HygroFlex transmitter range, which includes a selection of basic, multifunction, high-end, and ATEX devices.
