However, you should never, ever use a digital thermometer used to take body temperature to measure water. Those thermometers are built to measure body heat, which is cooler than the heat of boiling water. If you put it in a pot of hot water, it might shatter and seriously injure someone.
In this regard, can I use a meat thermometer for liquids?
(Put the thermometer into any liquid, like milk; 32° to 40° F is a safe range.)

Do thermometers work in liquid?
Glass bulb thermometers work because liquids, such as water, alcohol, or mercury, expand slightly when the temperature rises. If the liquid is trapped in a narrow tube, it has nowhere to go but up.
How do you clean a digital thermometer after use?

- Coat the entire body of the thermometer with the disinfectant solution, making sure to rub it in thoroughly.
How does a digital thermometer work without mercury?
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. A small computer or other circuit measures the resistance, and converts it to a temperature.
What do you do if you put water in a digital thermometer?
