RMS-HCD-S - Humidity and Temperature Probe

RMS-HCD-S - Humidity and Temperature Probe

The RMS-HCD-S digital probe is characterized by its high performance. Very low current consumption, the highest accuracy, and measurement results within 50 ms (electronics) are its outstanding features. This is due to the new AirChip4000, which together with the new HYGROMER® HT-1 sensor forms a powerful combination.


  • Measures relative humidity and temperature, calculates the dew point 
  • With new HYGROMER® HT-1 sensor
  • Outstanding accuracy and repeatability 
  • Accuracy ±0.8 %RH
  • Excellent long-term stability <1 %RH / year
  • Developed for very low power applications 
  • Digital calibration and adjustment
  • Compatible with RMS data loggers and RMS software
  • Conforms to FDA 21 CFR Part 11 / GAMP 5
