Several common thermometer
According to measurement experts, the most common glass thermometer thermometer , which allows the mercury rises with the temperature maintained their original position, to facilitate the user at any time observation. Due to the relatively dense structure of glass, mercury performance is very stable, so the glass thermometer has shown the value of accurate, high stability, and low cost, the advantages of no external power supply, the trust people, especially medical workers. But glass thermometer defects are more obvious, easily broken, mercury contamination may exist; measurement time is relatively long, acute and critically ill patients, the elderly, infants and other inconvenient to use, relatively trouble reading and so on.
With the development of science and technology, has a lot of new types of thermometers. Electronic thermometer use of certain physical parameters of the material (such as resistance, voltage, current, etc.) to determine the relationship between ambient temperature and the temperature is displayed in digital form, clear reading, easy to carry. Its disadvantage is that by showing the value of factors affecting the accuracy of electronic components and battery-powered status, as glass thermometer.
Ear temperature thermometer
Thermometer in the armpit general, oral, rectal, etc. used in practical applications, it is generally feel inconvenient or uncomfortable. The ear type thermometer for measuring the ear by the tympanic membrane radiance to achieve non-contact measurement of body temperature. Simply align the probe auditory canal, press the measure button, only a few seconds to get the measurement data, is ideal for patients with acute illness, the elderly, infants and other uses. However, in the initial period, users are not familiar with this mode of operation due, you may get several different measurement data, in general, the maximum value that is to be measured data. This would be more satisfied users are familiar with the thermometer.
