Rotronic HygroFlex-HF8
Description
the universal industrial transmitter
Problem-free, accurate humidity measurement results from the most stable sensor in the industry combined with our unique HygroClip® digital probe technology, designed to practically eliminate any maintenance downtime.
When it is time for a scheduled calibration ‘hot swap’ in seconds with a calibrated probe without loss of measurement accuracy. HygroFlex8 transmitters provide superb precision and state-of-the-art functionality, taking humidity and temperature measurement to a whole new level of performance and reliability (0.8 %rh and < 0.1 °C accuracy).
