Glass temperature gauge:
According to the measurement experts, the commonest thermometer is glass temperature gauge. The mercury column will surge with the increasing temperature. Though the glass thermometer can make this mercury column maintain the original place, which is convenient for the users' statement at any time. Since the structure on the glass thermometer is denser, the mercury performance is very secure. So the glass thermometer is actually showing advantages of accuracy, excessive stability, and low price with no external power supply, which is the winner the trust from folks, especially many healthcare employees. But the defects of it are usually obvious. It is easily cracked, and there is the possibility of mercury pollution. It deserves relatively long time to evaluate. It is not convenient to use for severely ill patients, the elderly, toddlers and young children. It is also hard to read the measurement.
Electronic temperature gauge:
With the development of science and technology, presently there are many new types of thermometers. From the certain relationships between many physical parameters (such as resistor, current, and current) and ambient heat range, electronic thermometer displays the particular temperature in digital style. It is clear to read, and straightforward to carry. Its deficiency is in that the accurate value is going to be affected by electronic components and also battery power supply condition. It really is inferior to the glass temperature gauge.
Ear thermometer:
The temperature gauge is usually used in the underarm, oral cavity and rectum. Used, people generally feel annoying or uncomfortable. Ear temperature gauge is measured through ray brightness of ear tympanic membrane layer, and it is non-contact measurement. People just need to put the probe to internal acoustic guitar meatus and press the key. After only a few seconds, they find the measured data. It is very appropriate for urgent seriously ill individuals, elderly, baby etc. Yet at the initial stage useful, because users are not quite familiar with this mode regarding operation, they may get a number of different measurement data. Generally the highest measured value is the comparatively right data. Users will likely be satisfied with the thermometer as soon as they are familiar with it.
Forehead temperature gauge:
Ear temperature and brow temperature are measured as a result of infrared temperature measurement. The problem that Infrared radiation irradiates your forehead surface and reactions to the forehead compares along with spectral temperature. Forehead temperature is over the above operation to get the precise temperature value. There are also great deals of infrared thermometers that can measure head temperature and forehead heat together.
