Thermometers is commonly used lab instruments for measuring
temperature and it changes with a high degree of precision and
accuracy. These instruments have to pass rigorous testing standards
because of the high level of accuracy required. Thermometers may be made
of glass or metal and then strengthened through thermal tempering or
annealing. Types of Thermometers
There are various types of laboratory thermometer available including:
- Liquid-in-glass Thermometers: These instruments are made of sealed glass, containing a fluid, either mercury or red alcohol.
- Bimetallic Strip Thermometers: These instruments have two different metals bonded together and expanding at different rates as they warm up.
- Infrared Thermometers: These non: contact equipment convert infrared (IR) energy into an electrical signal which is displayed in units of temperature.
