The new HygroFlex 4-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).

Features:

• Relative humidity, temperature measurement and dew point calculation
• Outstanding accuracy and repeatability
• Hygromer® IN-1 humidity sensor
• Auto-diagnostics and automatic correction
• Selectable and scalable analog outputs
• Various digital outputs available

Easy to read display

• Display of the measured values on a clear, backlit graphics display with trend indicators
• Configuration by keypad possible

Tried-and-tested housing

• Robust industrial housing
• Wall or duct mount versions

Output signals

• Two freely selectable and scalable analog outputs
• 2-wire and 3/4-wire systems available
• Optional digital outputs allow integration on a network via RS485 or Ethernet - wire or wireless

Fast response and precision measurement

• Integrated probe
• By decoupling the Pt100 temperature sensor from the probe, thermal response is significantly improved
• Heat from the electronic components is not transmitted to the sensors, thereby improving the accuracy of the system

AirChip3000 Technology

• 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

Applications

• The HygroFlex4-series is ideal for all applications where exact measurement of humidity and temperature is of decisive importance.
• The transmitters can be used in a variety of fields for heating, ventilation and air conditioning applications, greenhouses, museums,
• warehouses, libraries, railway stations and for climate control in office buildings.
• Thanks to the exceptional long-term stability of the sensors and auto-diagnostics, the transmitters are both service-friendly and
• reliable, thereby saving you time and money.
