What should I pay attention to when using temperature timing?

Best answer: The thermometer should be hung in 空 air, not touching the ground or other objects, not being exposed to sunlight, the thermometer should be kept dry, not being touched by water or other liquids, and wait for the thermometer to indicate the temperature before reading. Thermometers are tools that can accurately judge and measure temperature, and are divided into pointer thermometers and digital thermometers. A variety of thermometers have been designed and manufactured according to the difference of use purposes.

On October 16, 2020, the State Food and Drug Administration published the Notice of the General Division of the State Food and Drug Administration on the Implementation of the Minamata Convention on Mercury on its website. The Notice clearly requires that from January 1, 2026, China will completely ban the production of thermometers and sphygmomanometers containing mercury. A variety of thermometers have been designed and manufactured according to the difference of use purposes. The design basis is as follows: using the phenomenon that solids, liquids and gases expand with heat and contract with cold due to the influence of temperature; Under the condition of constant volume, the pressure of gas (or vapor) changes due to the difference of temperature; The effect of thermoelectric effect; The resistance changes with the temperature. The influence of thermal radiation, etc.
