HC2A-S3 - Standard meteo probe

The HC2A-S3 probe is the meteorological probe with a white housing - same specification overall as the HC2A-S probe but with a different filter (larger pore size suitable for meteorological applications). It measures relative humidity and temperature and calculates the dew/frost point.

Features of the meteorological probe

  • Accuracy: ±0.8 %rh, ±0.1 K, at 23 °C (10...30 °C)
  • Range of application: -50…100 °C / 0…100 %rh
  • Digital interface (UART) and scalable analog outputs, 0…1 V
  • Standard output scaling: 0…1 V = -40…60 °C / 0…100 %rh
  • Adjusted at 23 °C and 10, 35, 80 %rh

Advantages

  • Measures relative humidity and temperature
  • Outstanding accuracy, repeatability and long-term stability
  • Advanced probe housing and construction
  • Available with interchangeable sensor
  • Hot swappable, no calibration adjustment required due to the digital interface with Rotronic devices

Smart Electronic

  • Based on the Rotronic’s AirChip3000
  • Calculates the dew / frost point
  • Alarm generation
  • Saves adjustment data so that probes can be
  • interchanged without re-adjusting
  • Hot-swappable

Flexibility and Compatibility

  • User scalable analog analog ouput signals (2x 0…1V)1
  • Digital interface via UART2
  • Rapidly interfaced with HygroClip2 devices from
  • Rotronic or in OEM3 applications
