1, electronic thermometer
The electronic thermometer will be placed in the armpit, one or two minutes to know the body temperature. Compared with the traditional mercury thermometer, the electronic thermometer is fast, safe and convenient, suitable for the elderly and children.
The electronic thermometer, although no mercury, but once the electronic components are exposed to safety issues, especially to be careful of children biting through the battery liquid exposure. In addition, the electronic thermometer as a kind of electronic products, need to replace the battery often, the use of long time may also appear measurement is not allowed.
2, ear thermometer
With infrared ear thermometer to measure the body temperature only need to align the probe to the inner ear canal, a few seconds to know the body temperature, faster than the speed of the electronic thermometer. However, the accuracy of infrared ear thermometers is not much different from that of mercury thermometers because the ear cavity temperature and axillary temperature are closer to the actual body temperature, so the measurements are more reliable.
3, forehead temperature gun
Frontal temperature gun is widely used in hospital outpatient clinics, airports and so on. However, this thermometer is susceptible to the external environment and the skin surface dirt, sebum layer interference, and the forehead surface temperature and the actual body temperature there is a gap, which may result in inaccurate measurement. When operating the thermometer, the distance between the thermometer and the forehead can also affect the results.

Because of the toxicity of mercury, the banning and substitution of mercury thermometers has become the **** knowledge of the human society. 1992, Sweden has already banned the sale of all medical devices containing mercury. Britain, France, Denmark and the Netherlands have also banned the use and sale. In the United States, 13 states and cities, including San Francisco, Boston and Michigan, have banned the sale of mercury thermometers since 2000. The European Commission has also banned the sale of mercury thermometers since 2005 and banned their export since 2011.
In December 2008, the Argentine government also announced that it would ban the production and importation of mercury thermometers. The World Health Organization has also established the Global Mercury Elimination Program, which aims to reduce demand for mercury-containing thermometers and sphygmomanometers by 70 percent globally by 2017.
