The mechanical room hygro-thermostat HYGRASREG
®
RHT, a room hygro-
stat with (bi metal) temperature controller, is used for controlling and
monitoring the relative humidity (humidifying and dehumidifying) and the
temperature in office and residential rooms, baths, winter gardens, labs,
computer rooms, etc. HYGRASREG
®
RHT is applied in dust-free, pollut-
ant-free, non-aggressive air.
