Two models are available to meet different customer needs:

  • 3S-AT&RH-MB: Measures Relative Humidity and Ambient Temperature. It can be connected to SEVEN Irradiance Sensor or Sensor Box models.
  • 3S-RH/AT/PS-MB: Measures Relative Humidity, Ambient Temperature, and Pressure. It can be connected to the SEVEN Compact Weather Station.

The measured values can be transmitted to monitoring instruments, data loggers and other receiving units via the serial RS485 interface with MODBUS RTU protocol.
