Unlike the medical or clinical thermometer which is used solely to measure human body temperature, a laboratory thermometer has different uses.

A laboratory thermometer is used to measure the boiling point and freezing point during science experiments. It is also used to measure the temperature of substances. It measures temperature ranging between -10 degree Celsius and 110 degree Celsius.

 

Let’s take a look at different types of laboratory thermometers:

 

 

Liquid-in-Glass

Most thermometers usually fall in the category of science laboratory glassware as it made of glass. The laboratory thermometer can be easily identified through its long stem with a silver bulb at its bottom. The silver colour is nothing but mercury which expands as the temperature goes up and contracts as temperature goes down.

 

Infrared

This type of thermometer comprises a lens that focuses the infrared energy (IR) on to a detector. This detector in turn coverts IR into an electric signal that is further displayed in units of temperature. Its application is best suited for taking temperatures from a distance or measuring it from the surface.
