The Rotronic HygroFlex3-Series Humidity Transmitter is a state-of-the-art HVAC transmitter based on AirChip3000 technology. It features integrated sensors: the Rotronic Hygromer IN-1 humidity sensor and a Pt100 1/3 Class B temperature sensor. AirChip3000 compensates humidity and temperature over 30,000 reference points, maintains a 2,000-point data memory, and includes sensor auto-diagnostics and automatic correction.

The transmitter delivers accuracy of ±2.0% rh and ±0.3 K with a resolution of <0.02% rh and 0.01 K. Response time (τ 63) is less than 10 seconds, ensuring fast, reliable readings. The HygroFlex3-series is ideal for applications requiring precise humidity and temperature control, such as HVAC systems, greenhouses, museums, warehouses, libraries, railway stations, and office building climate control.

Active alarming, ASIC integration, and on-chip EEPROM are standard features of the AirChip3000 platform, providing exceptional performance and long-term stability.
