Several Common Thermometers

Glass temperature gauge:
According to the measurement experts, the commonest thermometer is glass temperature gauge. The mercury column will go up with the increasing temperature. Nevertheless the glass thermometer can make this mercury column maintain the original placement, which is convenient for the users' statement at any time. Since the structure from the glass thermometer is denser, the mercury performance is very firm. So the glass thermometer can be showing advantages of accuracy, substantial stability, and low price without having external power supply, which is victorious the trust from folks, especially many healthcare personnel. But the defects of it usually are obvious. It is easily busted, and there is the possibility of mercury pollution. It relatively long time to evaluate. It is not convenient to use for significantly ill patients, the elderly, toddlers and young children. It is also tricky to read the measurement.

Electronic temperature gauge:
With the development of science and technology, presently there are many new types of thermometers. Over the certain relationships between several physical parameters (such as resistor, current, current) and ambient temperatures, electronic thermometer displays this temperature in digital type. It is clear to read, and to carry. Its deficiency is in that the accurate value is going to be affected by electronic components as well as battery power supply condition. It's 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 awkward or uncomfortable. Ear temperature gauge is measured through the radiation brightness of ear tympanic tissue layer, and it is non-contact measurement. People just need to put the probe to internal traditional meatus and press the press button. After only a few seconds, they have the measured data. It is very ideal for urgent seriously ill individuals, elderly, baby etc. Yet at the initial stage of usage, because users are not quite familiar with this mode associated with operation, they may get a number of different measurement data. Generally the optimum measured value is the somewhat right data. Users are going to be satisfied with the thermometer once they are familiar with it.

Forehead temperature gauge:
Ear temperature and your forehead temperature are measured via infrared temperature measurement. The trouble that Infrared radiation irradiates this forehead surface and reactions to the forehead compares together with spectral temperature. Forehead temperature is over the above operation to get the exact temperature value. There are also many infrared thermometers that can measure ear canal temperature and forehead temperatures together.
