Are there thermometers without mercury?
There are non-mercury thermometers with temperature and accuracy ranges equal to most mercury thermometers. An exception is on the high end of the temperature scale. Until recently 260° C was the typical limit for non-mercury thermometers.
What is in a non mercury thermometer?
Spirit thermometers use a non-toxic alcohol instead of mercury to register the temperature. Digital thermometers contain a device called a thermoresistor. The thermoresistor has an electrical current running through it, and the resistance, or how freely the current can flow, changes with temperature.

How can you tell mercury from galinstan?
The non-toxic galinstan replaces mercury in thermometers; the tube interior must be coated with gallium oxide to prevent it from wetting the glass. Galinstan has higher reflectivity and lower density than mercury.
Which thermometer is best for Covid?
No-touch or non-contact infrared thermometers measure temperature through the forehead from a close distance in seconds. They may be used on newborns and older people. They’re easy to use and may reduce the risk of spreading disease by allowing more physical distancing.
