Laboratory thermometers are specifically designed to measure temperature or temperatures with a high degree of precision. Laboratory thermometers are mostly made of glass or metal and are strengthened through thermal tampering and annealing processes. A vast variety of laboratory thermometers are available in the market today. These modern laboratory thermometers are made of sealed glass and contain liquids such as mercury or red alcohol, which has the ability to change its volume relative to its temperature. Another type of laboratory thermometer is the bimetallic strip thermometer, which includes two different metals that are bonded together and expand at different rates as they warm up. With the help of laboratory thermometers one can measure temperature in either fahrenheit or celsius.
