## Description

Mechanical temperature controller with rotary adjustment and probe, ideal for household appliances and industrial equipment, maintains stable temperature through precise switching. Operates at 250VAC and 16A, covers the range 50-300°C, has robust metal construction and ceramic components, includes 70 cm capillary and fast response probe for efficient control.
Adjustable temperature controller, suitable for a wide range of applications in household appliances and industrial equipment. It has a robust structure and includes a temperature sensor with a fast response.
It works on the principle of expansion and contraction of the working fluid in response to temperature changes, operating a switch to maintain constant temperature.
The liquid is integrated into the tube connecting the probe to the regulator, which is why it is essential that it is not deformed in such a way as to restrict the fluid inside. Repeated deformations can also lead to perforation of the tube and, implicitly, to the thermostat ceasing to function.
