The HC2A-S3A probe is the meteorological probe with a white housing but with a different filter (Wire-mesh filter with 10 µm filter pore size suitable for meteorological applications). It measures relative humidity and temperature and calculates the dew/frost point and is designed for the use in Rotronic meteorological applications.

Features of the meteorological probe

• Accuracy: ±0.8 %rh, ±0.1 K, at 23 °C (10...30 °C)
• Range of application: -50…80 °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

Advantages

• Especially designed for the use in meteorological applications
• New humidity sensor HYGROMER HM1-SK
• Outstanding accuracy, repeatability and long-term stability
• 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
• 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 UART
• Compatible with Rotronic devices HF5, HF8 and HP32
