Level of liquid or gas in the tube â The appropriate volume of liquid or gas in the tube depends on the expansion coefficient of the substance used, the area of the capillary and the range of temperature required. Bimetal or bi-metallic thermometers use a bimetal spring as the temperature-sensing element.
They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns, to describe the device's ability to measure temperature from a distance. non-adjustable thermometer may be used to measure the temperature of a reflective surface by applying a non-reflective paint or tape, with some loss of accuracy. A sensor with an adjustable emissivity setting can also be used to calibrate the sensor for a given surface, or to measure the emissivity of a surface.
