Bi-metal thermometers use a long probe (the stem) to transfer the heat to a coil just behind the dial which expands or contracts according to the temperature it is exposed to. The dial of the bi-metal thermometer then displays the temperature.
Our range of Bi-metal thermometers caters for all applications and industries as well as home use. The Bi-metal thermometer is durable and has a wider temperature range then many other thermometers.
