Unmatched High Accuracy for Indicators, Transmitters or Data Loggers

The HC2-SH / HC2-S3H fulfills the most stringent requirements of any application with very high accuracy. It measures humidity and temperature and calculates the dew/frost point.


Accuracy: ±0.5 %RH, ±0.1 K, at 23 °C ±5 K
Range of measurement: -50â¦100 °C / 0â¦100 %RH
Digital interface (UART) and scalable analog outputs, 0â¦1 V
Standard output scaling: 0â¦1 V = -40â¦60 °C / 0â¦100 %RH
Adjusted at 23 °C and 10, 20, 30, 40, 50, 60, 70, 80, 90 %RH, then calibrated at 20, 50, 80 %RH
