What are the types of thermometers? How to use a thermometer?

There are infrared, mercury, electronic types, forehead thermometers, and ear thermometers, these types, when using mercury type, you need to put it under the armpit, other types need to measure the temperature of the forehead, or measure the temperature of the ear.

There are several types of thermometers: mercury thermometer, electronic thermometer, infrared thermometer, these are the more common thermometers, the thermometer is generally used under the armpit, and there are also contained in the mouth.

There are many types, including electron type, infrared, mercury type, and one that measures the head, or the hand, and when you use it, you need to put it under your armpit and wait for 10 minutes to take it out.

There are many types of thermometers, the more common ones are glass thermometers and electronic thermometers.

A glass thermometer (medical thermometer) is placed only under the armpit to measure the temperature. The thermometer is placed in the armpit, the armpit is tightly closed, taken out after 5 10 minutes, viewed horizontally, the thermometer can be rotated slightly when checking the degree, the mercury can be clearly seen, and the mercury column with the increase in body temperature remains in its original position, which is convenient for users to observe their body temperature at any time.

The electronic thermometer can be placed under the armpit or in the oral cavity to measure the temperature, the temperature will be displayed on the electronic display screen after the temperature measurement, the electronic thermometer is the use of the temperature sensor to output electrical signals, directly output digital signals or then convert the current signal into a digital signal that can be identified by the internal integrated circuit, and then display the temperature in a digital shape through the display, which can record and read the highest value of the temperature measured by Xianghui.

1. Mercury thermometer. A mercury thermometer is a traditional thermometer made of glass with a column of mercury that rises with body temperature. Mercury thermometer has the characteristics of accurate measurement results, high stability, and low cost.

Mercury is stored inside the mercury ball at the end. When mercury is heated, it expands, rising along a very narrow glass tube. Therefore, a small change in body temperature can cause a large increase in mercury in the glass tube.

After taking your temperature, shake the thermometer vigorously to return the mercury to the ball.

2. Electronic thermometer. An electronic thermometer uses the physical parameters of certain substances, such as resistance, voltage, current, etc., to display the body temperature in the form of numbers. The electronic thermometer is easy to read, the measurement time is short, and it does not contain mercury, which is harmless to the human body and the surrounding environment.

The disadvantage is that the accuracy of the indication is affected by factors such as electronic components and battery power supply, which is not as good as that of a glass thermometer.

3. Infrared thermometer. Infrared thermometer lifting and grinding is to measure body temperature through infrared, which can be divided into two types: contact and non-contact compared with electronic thermometer. Contact infrared thermometers are commonly used ear thermometers, forehead thermometers, and multi-function thermometers, which can measure accurate body temperature from the ear in just one second.

The most common non-contact infrared thermometer is a forehead thermometer, which can measure the temperature of the human body from a distance. Just aim the probe at the forehead, press the measurement button, and the measurement data can be obtained in just a few seconds, which is very suitable for patients with acute and serious diseases, the elderly, infants and young children.

4. Intelligent electronic thermometer. Aoyuanyuan wireless intelligent electronic thermometer, contact temperature measurement design, using adhesive stickers (made of medical-grade dressing materials) to wear on the baby's armpits, wait for 1-2 minutes after the end of the temperature measurement, and check the body temperature data on the mobile phone APP. Lightweight non-inductive wearing, no roughness to the touch, no odor on the smell, and the baby's degree of cooperation is relatively high.

Because of its small size, the battery used is also the smallest type of button battery, the overall power consumption is extremely low, and the continuous use time can be up to a week, which is more suitable for babies.

1. The glass thermometer is the most common thermometer, which can keep the mercury column in its original position as the body temperature rises, which is convenient for users to observe at any time.

2. The electronic thermometer uses the definite relationship between the physical parameters of certain substances and the ambient temperature to display the body temperature in the form of numbers.

3. The infrared thermometer measures the temperature of the human body by measuring the radiation temperature of the eardrum or forehead.

1. The glass thermometer has the characteristics of accurate indication and high stability, as well as the advantages of low cost and no external power supply.

2. The electronic thermometer has the advantages of clear reading, easy to carry and simple imitation, and short measurement time.

3. The infrared thermometer is convenient to operate and quick to measure, but it also has the disadvantages of being expensive and requiring high ambient temperature when using.
