A household thermometer is a practical tool that can help people better understand and grasp the temperature situation of their environment, and take corresponding measures to maintain a comfortable and healthy environment.

It should be noted that when using a household thermometer, it should be ensured to operate correctly according to the instructions and avoid exposing it to extreme temperatures or humid environments to ensure the accuracy of its measurement results. Meanwhile, for certain special types of thermometers, such as mercury thermometers used to measure human body temperature, they should be handled properly after use to avoid environmental pollution.
