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:
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.
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.
