Standard Humidity Probes - Rotronic HC2A-S(S3),-SM,-HH

High Accuracy Humidity and Temperature Measurement


  • Range of application -50…100 °C / 0…100 %RH
  • Accuracy: ±0.8 %RH, ±0.1 K, at 23 °C ±5 K
  • Digital interface (UART) and scalable analog outputs, 0…1 V
  • FDA 21 CFR Part 11 and GAMP compatible (HW4 Software)

The standard Rotronic Humidity and Temperature probes can be used in application with temperature from -50…100°C / 0…100 % RH. With an outstanding accuracy ± 0.8% RH ±0.1°C. For calibration the probes can be replaced without almost any downtime. Together with a Rotronic HF5/8, PF4/5 transmitter or HP32 and HP23 this probe is the first selection for many applications.

Versatile Humidity Probe HC2A-S and HC2A-S3
The HC2A-S/-S3 are the most sold versatile probes from Rotronic and form the basis of the product portfolio. They measure humidity and temperature and calculate the dew/frost point.

Applications for the Humidity Sensors HC2A-S/-S3:
Both humidity sensors are used for HVAC, food industry building services equipment, paper, textile and pharmaceutical industries. The HC2A-S3 version with its white body is additionally used for meteorology.

Robust Humidity Probe HC2A-SM
The HC2A-SM is the robust probe from Rotronic for harsh environments and adds to the wide product portfolio. It also covers humidity and temperature measurement and dew/frost point calculation.

Applications for the Humidity Sensor HC2A-SM:
Food, paper, textile, pharmaceutical and cosmetic industries
