Mechanical room thermostat for industrial use. Due to the high degree of protection, the device can be used in humid rooms and in animal breeding applications. The room thermostats are also suitable for temperature monitoring in greenhouses.


The temperature measured at the probe causes a change in the volume of the measuring liquid. Electrical switching is triggered by the force acting.
