Thermometers are not designed to last for a long time, and they will eventually break down. However, it is possible to extend the life of your thermometer by taking care of it properly.
Thermometers are designed to be used for a short period of time before they break down or malfunction. To extend the life of your thermometer, keep it out of direct sunlight and away from extreme temperatures. Also, keep it in a cool place when you’re not using it. Do not store liquids or chemicals near the thermometer as well.
