Glass Thermometers

Glass Thermometers It is a thermometer that works by changing the mechanical properties with the expansion principle or liquid contraction When the platelets are heated, the temperature rises And shrink when the temperature drops It is contained within the closed glass tube. The liquid used must not be changed in use

In general, there are two types of mercury thermometers: mercury and alcohols. If you want to measure in the low temperature zone should use alcohol. Alcohol is more sensitive to temperature changes. And cheaper than mercury. For use in high temperature areas should use mercury. Because mercury can withstand higher temperatures.
