Rotronic HygroFlex3 Humidity & Temperature Transmitter
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).
Features
- Relative humidity, temperature measurement and dew point calculation
- Outstanding accuracy and repeatability
- Hygromer® IN-1 humidity sensor
- Auto-diagnostics and automatic correction
- Freely selectable and scalable analog outputs
- Also available as hygrostat and thermostat
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 temperature
over 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 |

Ordering Codes Notes:
- Output 1: relative humidity or dew point
- Output 2: temperature
- The dew / frost point range uses the same unit (˚C or ˚F) as the temperature output. The factory default setting is frost point below freezing
- Custom range: be sure to clearly specify the desired range at the time of the order. When a special range has been ordered, the letters ST, XSC or S are used in columns 4, 6 or 7 in the above table. These generic codes will be replaced with a specific code only for quantity and repeat orders
- Use column 4 to specify the unit system (M or E) when temperature is not one of the analog outputs
