Steel Humidity Probe – Rotronic HC2A-SM

Ultra stable, accurate and versatile probe for Termperatures -50…100°C


  • 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
  • GAMP compatible (HygroSoft Software)

The standard Rotronic Humidity and Temperature probes can be used in application with temperatures from -50…100 °C / 0…100 %RH. With an outstanding accuracy of ± 0.8 %RH / ± 0.1°C. For calibration purposes the probes can be replaced without almost any downtime. Together with a Rotronic HF5, PF4/5 transmitter or HP32 the HC2A-SM probe is the first selection for many applications.

The HC2A-SM is the most sold probe from Rotronic in pharmaceutical, cosmetical and food applications due to the used stainless steel 1.4301 and meets the requirement of many national and international standards and food processing and manufacturing. They measure Humidity and Temperature and can calculate the dew-/ frost point.
