Rotronic Sensor HC2-S

Rotronic sensor HC2A-S

Based on the Airchip 3000 Technology, the HygroClip 2 probes can be used for control of temperature and humidity. The HygroClip 2 probes can be configured with the ROTRONIC HW4 software and share the following features:

  • Measurement of relative humidity and temperature
  • Data recording of up to 2000 relative humidity and temperature value pairs
  • Programmable automatic sensor test with fail safe mode and sensor drift compensation
