• Glass thermometer

According to measurement experts’ introduce, glass thermometer is the most common thermometer. It allows the mercury column with the temperature’s rise to maintain their original position. Because the structure of glass is very intensive and the function of mercury is very stable,so Glass-stem thermometer has the features of accurate and stabilization,in addition,it also has the advantages of cheap,no exterior power source,which is served most people especially the medical professional workers. But the glass thermometer also has obvious advantages: easily broken and the possibility of mercury pollution; its relatively long measurement time is inconvenient to acutely and seriously ill patients, the elderly, infants and children and it takes troube to read the number.Who’s Most Superior of Them All?

• Electronic thermometer

With the development of the scientific technology, a lot of new type thermometers have appeared nowadays. Electronic thermometer uses the existing fixed relation between physical parameter (like electric resistance, voltage, electric current, etc.) of some substances and the temperature of the environment to display the body temperature in the form of figure. Therefore the number is clear to read and it is convenient to carry. Its flaw is that the accuracy of tested temperature is easily affected by electronic components and the condition of power supply,which is not as good as the Glass-stem thermometer.

• Lug Thermometer

The thermometer is commonly used in the places like the armpit, the mouth and the rectum, making people feel uncomfortable in using. By measuring the radiance of the ear tympanic, the ear thermometer can finish the measurement in a non-contact way. You only need aim the camera to the internal acoustic meatus and press the measure button, and then you’ll get the data after several seconds. It suits those special people like the critically ill patients, the elderly, and the babies perfectly. But in the initial period, because the user is not quite familiar with this operation method,he may get several different measurement data.In general, the measured maximum value is the desired data.The user will be quite satisfied with this kind of thermometer after he gets familiar with it.

• Slice thermometer

The continuous development of new technology has also brought a kind of very peculiar thermometer which can be called chip-type thermometer or dot-matrix thermometer. This type of thermometer has the size of visit card. It is 6~7cm long, about 0.5cm wide. And there are some tidy round dots with numbers on it. After conducting temperature test, the dots below the certain numerical value will dim, while the remaining dots can’t change, the user can determine body temperature according to the above changes. This thermometer isn’t expensive, it is small size and easy to carry and store, its pollution is very small, especially for medical institutions, it can be disposable and avoid cross-infection.

Experts says that glass-stem thermometer is national compulsory measuring instrument of verification, and it is with long history of production and application, not only its product quality but also its monitoring and surpervision are standard. But many Digital thermometer,Ear-thermometer appear in the market as health products and presents, they always have no intensive and effective administration of national related departments.

Experts warn that if consumers want to use the digital or ear thermometer to measure body temperature, they should pay attention to the following aspects:

• Because the requirement of body temperature test is quite strict and generally demands the thermometer’s indication error is ±0.1°C, the accuracy of thermometers consumers select and buy must meet this requirement.
• Please read the operating instruction carefully, especially the key points of operation. Before you use it you can compare it with Glass-stem thermometer,so that you can ensure to operate correctly.
• When taking the armpit measurement, you must grip it firmly to make sure the thermometer be in full touch with the body. When taking the mouth measurement, you must put the thermometer under your tongue and press it with certain force, and must clean and sterilize it after using.
• No matter what kind of thermometer you select, you’d better use one per person at one time in order to avoid cross infection.
