The Rotronic HygroFlex3 measurement range is -40 to 140ºF (-40 to 60ºC) / 0 to 100%RH with the accuracy of ±2 %RH / 0.3ºC at 23±5ºC.
The HF3 transmitter is designed for fixed installation and it comes with an AirChip3000 chip inside the unit. The chip allows the instrument to achieve a degree of accuracy not seen before. The HF3 transmitter with the combination of advances in sensor technology and integration provides superb precision and state-of-the-art functionality, taking humidity, temperature and dew point measurement to a whole new level of performance and reliability (< 2 % rh / 0.3 K).
Highly versatile • One or two selectable and scalable analog outputs • Analog outputs assignable to relative humidity,temperature or dew point • 2-wire or 3/4-wire systems available • Available with two integrated relay contacts for use as a thermo-hygrostat
AirChip3000 • Compensates humidity and temperatureover 30,000 reference points • 2,000 data point memory • Dew/frost point calculation • Sensor auto-diagnostics and automatic correction • Active alarming and information • ASIC (Application Specific Integrated Circuit), micro-controller and EEPROM on one chip
Fast response and precision measurement • By decoupling the Pt100 temperature sensor from the probe, thermal response is significantly improved • Use of Pt100 1/3 Class B sensors for maximum accuracy
