The thermometer is a maximum thermometer, also known as the medical thermometer, Guangdong and Hong Kong and Taiwan is called the heat probe, which can record the thermometer had measured the highest temperature. The state regulations since January 1, 2026, China will completely ban the production of mercury-containing thermometers and mercury-containing sphygmomanometer products.
The working substance of the thermometer is mercury, which has a much larger glass bubble volume than the volume of the thin tube above it. The mercury in the bubble produces small changes due to the influence of body temperature, and the expansion of the volume of mercury causes a significant change in the length of the mercury column in the tube.
Thermometer classification
1, glass thermometer: stable, accurate, inexpensive and so on, the disadvantage is easy to break, easy to cause is mercury pollution.
2, electronic thermometer: mainly the use of temperature sensors and integrated circuits, etc., to measure the body temperature, with convenient, safe and so on. However, the accuracy of electronic thermometer is not as high as glass thermometer, and the measuring part is mostly chosen in the forehead and wrist area.
3, multi-function infrared thermometer: mainly to measure the brightness radiated by the tympanic membrane of the ear, but also the circulation of blood in the subcutaneous arteries, the infrared light emitted by the measurement, more suitable for the elderly and infirm, as well as infants and young children.
4, the piece of thermometer: belongs to the new thermometer, the thermometer is covered with dots, according to the patient's body temperature changes in color changes, and then determine the body temperature. With easy to carry, small pollution and other characteristics.
