Rotronic HF4 Series (Wall & Duct Type)

The new Rotronic HF4 Series is the latest development in HVAC transmitters for relative humidity, temperature and dew point. Based on AirChip3000 technology, the instruments achieve a degree of accuracy not seen before. In combination with advances in sensor technology and integration, the HygroFlex HF42, HF43 and HF45 transmitters provide superb precision and state-of-the-art functionality, taking humidity, temperature and dew point measurement to a whole new level of performance and reliability (< 1 %rh / 0.2 K). Easy to read display:Display of the measured values on a clear, backlit graphic display with trend indicatorsConfiguration by keypad possibleTried-and-tested housing:Robust industrial housingWall or duct mount versionsOutput signals:Two freely selectable and scalable analog outputs2-wire and 3/4-wire systems availableOptional digital outputs allow integration on a network via RS485 or Ethernet - wire or wirelessFast response and precision measurement:Integrated probeBy decoupling the Pt100 temperature sensor from the probe, thermal response is significantly improvedHeat from the electronic components is not transmitted to the sensors, thereby improving the accuracy of the systemAirChip3000:Compensates humidity and temperature over 30,000 reference points2,000 data point memoryDew/frost point calculationSensor auto-diagnostics and automatic correctionActive alarming and informationASIC (Application Specific Integrated Circuit), micro-controller and EEPROM on one chip
