Bimetal dial thermometer Contact thermometer Tube thermometer 120C Thermometer Features: The dial thermometer is mounted using the spring included in the set. The length of the spring without expansion is 6.5 cm - suitable for standard pipes. The spring is also a measuring system, it consists of two metal plates with different expansion coefficients, which are firmly connected to each other (forming a bimetal). Temperature changes cause the bimetal strips to adapt mechanically to the shape of the pipe and consequently rotate. When one end of the bimetal measuring system is fixed, the other end rotates the pointer shaft. ZINC PLATED STEEL - Thanks to the material from which the thermometer is made, it will serve for many years. ACCURATE MEASUREMENT - it works every 1 C allows you to accurately control the temperature. APPLICATION - used to measure the temperature of gases and liquids in industry. It is a useful product for installation in pipelines, tanks and heating systems and installations. SPECIFICATION - Material: galvanized steel Measuring range: 0-120 C Graduation: 1C Spring length without extension: 6.5 cm Sensor position: rear Dimensions (length / width / height): 6.3 / 6.3 / 1.5 cm Weight: 54g.
