Bi-metal thermometer temperature gauges


Labfacilityhas introduced a new range of bi-metal stainless steel thermometers that are suitable for air, oil, water and other non-erosive fluids. Manufactured in the UK, the gauges offer Class 1 accuracy and temperature ranges from -20°C to 200°C.

Labfacility now offers Bi-Metal Stainless Steel Thermometers with bottom or back entry and ‘any-angle’ versions available to buy direct from the company’s website.

How does a bi-metal thermometer work?

The bi-metal thermometer is made up of two metals moulded together to form a coil. As the temperature changes, the bi-metallic coil contracts or expands, causing the pointer to move up or down the scale.

Advantages of bi-metal thermometers

There are many advantages of bimetallic thermometers compared to standard thermometers. Labfacility’s bi-metallic thermometers are available with wide temperature ranges from -20°C to 200°C. The gauges are easily installed and maintained. Manufactured in the UK, the gauges are formed of a rugged stainless-steel case and bayonet bezel with 316 stainless steel stems. The thermometers have a 100mm face size and are available in various lengths and diameters, customisable on the Labfacility website. Additionally, the bi-metallic thermometers benefit from Class 1 accuracy. All available options are configurable online. The bi-metallic thermometers have a lead time of only three to four weeks. Labfacility offer a one year guarantee for working parts/default. The company also offers the option of a certification of calibration.


Standard stainless-steel gauges and pockets are suitable for air, oil, water and other non-erosive fluids. The gauges can be used in many industries including the food, dairy, brewing, chemical, and oil industries, as well as in temperature controlled environments. Environmental conditions should be taken into account when considering suitable materials for the dial case.

The instrument head should be protected from localised heat or cold sources as this can lead to indicating errors. The function of the gauge does not require any special maintenance procedures but frequent checks must be made to ensure that the instrument is still working correctly and accurately. Any shift in temperature readings greater than twice the tolerance of the instrument must be investigated and the gauge should be replaced immediately if it is faulty.
