An accurate reading of a person’s temperature is a vital tool in managing illness. Temperature measurement equipment has become a necessary tool for epidemic prevention and control. In particular, infrared thermometers have become the first choice for preliminary temperature screening due to their convenience and speed. However, infrared thermometers have high environmental requirements, and deviations are prone to occur if they are not used properly. There are so many kinds of medical thermometers in the market. Some medical thermometers are used by doctors, some are invented for home use and others are used in other places. Are you familiar with the medical thermometers? I’d like to expand on the medical thermometers next to help you have a better understanding of the medical thermometers.


   Here is the list of the article:

What should you pay attention to before using the medical thermometer?

It is easy to determine whether you have a fever by checking your body temperature with a medical thermometer. Fever is an increase in body temperature, usually caused by infection. Although fevers can be uncomfortable, they are a sign that the body is fighting infection.

Normal body temperature is about 98.6 degrees Fahrenheit (°C) or 37 degrees Celsius (°C). The normal temperature change is usually 1° to 2° Fahrenheit (½° to 1° Celsius). The normal temperature is usually lower in the morning and higher during the day. In the afternoon or in the evening, the body temperature is the highest of all day.

The temperature of an adult fever is 100.4°F (38°C) or above. You can treat it at home with fever-reducing drugs and liquids to make yourself more comfortable or let it go on. But if it reaches 102°F (38.8°C) or higher, and home treatment does not reduce it, please call your healthcare provider

What types of medical thermometers are there?

Glass thermometer

The glass thermometer is the most common medical thermometer, which can keep the mercury column in its original position with the increase in body temperature and it is convenient for users to observe at any time.

Electronic thermometer

The electronic thermometer uses the definite relationship between the physical parameters of certain substances (such as resistance, voltage, current, etc.) and the ambient temperature to display the body temperature in digital form.

Multifunctional infrared thermometer

The multifunctional infrared thermometer can measure both ear temperature and forehead temperature.

Tablet thermometer

The continuous development of new technology has brought about a very peculiar thermometer, called a chip thermometer or a dot matrix thermometer. This kind of thermometer is only the size of a business card, 6-7 cm long and 0.5 cm wide, and it is covered with neatly arranged dots with numbers. After the body temperature test, the dots below a certain value will all darken, while the color of the other dots remains unchanged, and the user can determine the body temperature based on the above changes.

What are the advantages and disadvantages of these medical thermometers?

Because the structure of glass is relatively dense and the performance of mercury is very stable, the glass thermometer has the characteristics of accurate indication, high stability, and the advantages of low price and no external power supply. It is deeply trusted by people, especially medical workers. However, the defects of glass thermometers are also obvious. They are easily broken and may be contaminated by mercury. The measurement time is relatively long. It is inconvenient to use for patients with acute and serious illness, the elderly, infants, etc., and the reading is more troublesome.


The electronic thermometer has clear readings and is easy to carry. The disadvantage is that the accuracy of the indication is affected by factors such as electronic components and battery power supply, and is not as good as glass thermometers.

It can quickly and accurately measure human body temperature. Compared with traditional mercury glass thermometers, it has the advantages of convenient reading, short measurement time, high measurement accuracy, memory and buzzer prompts. The electronic thermometer does not contain mercury and is harmless to the human body and the surrounding environment. It is especially suitable for use in homes, hospitals and other occasions.


The ear temperature is very suitable for acute and serious patients, the elderly, infants and young children. However, in the initial stage of use, users may get several different measurement data because they are not familiar with this operation method. Generally speaking, the measured maximum value is the desired data. Both fear temperature and forehead temperature are measured by infrared. Forehead temperature is collected on the forehead, which is convenient, simple, and quick. Generally, a few seconds of measurement time is sufficient, and it is quite accurate. However, it is highly professional, inconvenient to popularize, and is not suitable for home users. Moreover, when the room temperature exceeds 25 degrees Celsius and the room temperature is below 20 degrees Celsius, the forehead thermometer is easily affected by the ambient temperature, including sweating, blowing and turning on the air conditioner. Partial collection temperature has a certain influence.


The chip thermometer is inexpensive, small in size, easy to carry and store, and has very little pollution. It is especially suitable for medical institutions and can be used at a time to avoid cross-infection.
