The newest addition to the Fandis family of thermo-regulators is a mechanical hygrostat, developed and produced in its laboratories. This thermo-regulator has been renewed fundamentally in the aesthetical aspect, engineering a more fashionable design with rounded shapes and optimizing visually the temperature setting system by pad printing of the values directly onto the housing. The new change-over hygrostat is suited for application on 35mm DIN rail and offers a setting range from 10 to 90% relative humidity, satisfying the demand of the industrial automation sector.
