Air Humidity Meter in a compact design / Modbus RTU interface /
measures air humidity, temperature / calculates the dew point and absolute humidity
The Air Humidity Meter measures air humidity and air temperature. The Air Humidity Meter calculates the dew point and the absolute humidity from these two values. The measurement data from the Air Humidity Meter are output via the Modbus RTU interface. This makes the Air Humidity Meter suitable for mass applications where the humidity and temperature must be measured quickly and easily.
Due to the compact dimensions, the Air Humidity Meter can be easily installed in control cabinets, on walls or in cavities. Optional filters protect the sensor element from the Air Humidity Meter from external influences such as moisture or dust. A simple cable connection creates the connection between the Air Humidity Meter and a Modbus master. The Air Humidity Meter can be used in conjunction with a Modbus display, a Modbus data logger or a paperless recorder.
