Humidity measurement for interiors and exteriors.

The WE720 meter has been designed for control of relative humidity for indoors and outdoors. Relative humidity indicates the percentage ratio between the amount of steam contained in a mass of air and the amount of saturation that the volume of air can contain, under the same temperature and pressure conditions. Normally the relative humidity trend is inverse to that of the temperature.
The sensor that detects the humidity is able to measure the variations and is composed of a capacitive element and a linear amplifier, which outputs an electrical signal 4-20mA, proportional to the relative humidity.
A screen is available for outdoor use to protect the sensor from adverse weather conditions.
