EnvMeter-485 PRO Temperature & Humidity Sensor

Envmeter-485 Pro is a temperature and relative humidity sensor for meteorological use with RS485 Modbus output

With quick and easy installation and very low power consumption. It is based on a top of the range hygrometer and a microcontroller that manages the information and transmits it in RS485.

Envmeter-485 Pro is available in two versions:

  • standard version;

with a thermohygrometric sensor.

  • professional meteorological use version;

with two thermohygrometric sensor direct on opposite faces of a vertical plane, the returned value is given by the average of the two sensors.
