Is the electronic thermometer accurate, is the electronic thermometer accurate?

The electronic thermometer is accurate.

In general, electronic thermometers are still relatively accurate, and electronic thermometers have many advantages over mercury thermometers. In terms of measurement time, the electronic thermometer only needs more than ten seconds, the measurement time is fast, the reading is also more convenient, can be remembered and has a prompt function.

There are many types of electronic thermometers, such as armpits, oral dual-use, armpit single-use, oral single-use, and ear-type measurement, which are much more convenient in comparison. However, when using an electronic thermometer, you should still pay attention to read the instructions carefully to avoid inaccurate temperature measurement.

Meaning:

When using an electronic thermometer, especially a non-contact electronic thermometer, choose indoor measurement as much as possible, and use an ambient temperature between 10 and 40. It is best to leave the electronic thermometer in the measurement environment for more than 30 minutes.

It doesn't matter whether you change it or not, you take a mercury thermometer as a measurement mark, see how much your electronic thermometer is different from it, measure it several times, pay attention to the measurement must be careful, the same position is repeatedly measured 5-6 times, about 2 minutes, and then take the average value of each measurement result, calculate the error, and then use the electronic in the future to artificially add this value to the measurement results, or to ensure accurate use.

If the electronic thermometer can be used correctly, its accuracy is still very high, there is no problem to meet the needs of daily life, and it is relatively simple to use, reading and carrying are simple. Since it does not contain mercury, it is also relatively safe. An electronic thermometer is composed of a temperature sensor, a button battery, an application-specific integrated circuit, a liquid crystal display and other electronic components, which can quickly and accurately measure the body temperature of the human body.

Compared with the traditional mercury glass thermometer, it has the advantages of convenient reading, high measurement accuracy and short measurement time, and does not contain mercury, which is not harmful to the human body and the surrounding environment, so it is especially suitable for families and is more suitable for use in hospitals and other occasions. The use of electronic thermometers and precautions are actually similar to those commonly used mercury thermometers. It is more in line with the use habits of the public, and the accuracy of measuring temperature is also relatively high.

In addition, like mercury thermometers, it can be affected by diet, exercise, bathing, etc.

Accurately, when used correctly, electronic thermometers are highly accurate, sufficient for daily needs, and safer than mercury thermometers.

There are two common types of electronic thermometers, including forehead thermometers and ear thermometers. The forehead thermometer is used to measure the temperature of the forehead, and the measurement results of the forehead thermometer are greatly affected by the external environment, and are often used for rapid screening of fever. An ear thermometer measures the temperature of the eardrum, and if done properly, the body temperature measured by the ear thermometer is relatively accurate.

When using an ear thermometer, it is necessary to keep the ear canal clean and know the correct measurement method, so that the body temperature can be measured reliably.

The correct way to measure with an electronic thermometer.

When measuring body temperature, the temperature will be affected by the temperature measurement time, outside air, and different body parts, which may cause the temperature to fluctuate. In order to get accurate temperature measurement data, please always maintain a certain temperature measurement area. When the armpit is underarmpit, the electronic thermometer should be close to the temperature sensing area; Under the tongue, the electronic thermometer should be inserted snugly at the base of the tongue.

Precautions. When the rear position of the electronic thermometer shows " ", it means that the battery needs to be replaced, and the battery adopts AG3 button battery or SR41 silver oxide battery. When replacing the battery, first open the upper battery cover. Press down the switch guide skin and then dial out the movement, about to dial out the movement can not be exceeded, and use a small bottle screwdriver to remove the battery.

Insert the new battery, positive side up, tuck into the movement, and carefully close the battery cover.

Which is accurate for measuring body temperature, electronic thermometer or mercury? I also just knew, don't buy blindly after reading it.

.Electronic thermometer. Questions. The armpit temperature of a normal person is 36 to 37 degrees, and the temperature of the human body is relatively constant, and the body temperature of a normal person fluctuates slightly within 24 hours, and the difference is generally not more than 1 degree. If you have a normal temperature, there is a problem with the thermometer.

I went to the pharmacy and measured it with an electronic thermometer for two days in a row, and then I bought some cold medicine, and today I felt that I couldn't bear it, and I went to another pharmacy to measure the mercury thermometer and almost hung up, thinking about it, I was really scared, and no one in the rental house would know about it.

I'm really not sure, I'm more than 38 degrees, and it took ten minutes for the fuck to show it.

Hello, 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 the form of numbers, with clear readings and easy to carry. 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.

Not very accurate, generally 1-2 degrees lower than the armpit with a thermometer.

1. Before use, the fullness of the electronic thermometer should be adjusted, the switch of the temperature measuring area should be placed at 0 30, and the LCD screen should display the ambient temperature. Press the calibration knob and adjust the full knob so that the reading is 30. Depending on the measuring temperature zone, the range switch can also be placed in the -30 0 position during calibration.

2. When measuring the surface temperature of the refrigeration system, the sensor of the electronic thermometer should be in close contact with the measured position, and the sensor of the electronic thermometer should be placed in the middle of the space when measuring the air temperature.

3. When using, be careful not to make the sensor collide with the pipeline and other parts to avoid damage.

4. If the handwriting of the display is unclear or the fullness cannot be calibrated during use, the battery of the thermometer should be replaced in time.

5. When not in use, it should be placed in a dry, cool and ventilated place.

In fact, the electronic thermometer and the traditional mercury measurement results are almost the same, but because the technology of the mercury thermometer has been very mature, and the technical content is relatively small, so the general small workshop made the "copycat" goods will not be bad, on the contrary, the electronic components of the electronic thermometer can be described as a penny of a penny, so the measurement results of a thermometer of more than ten yuan and dozens of yuan or even hundreds of yuan are absolutely different; At the same time, if the battery is low, it will also affect the accuracy of the measurement. Therefore, it is not appropriate to just say whether the electronic thermometer is accurate, but in comparison, the electronic thermometer is more convenient to use, and I believe that many people do not know how to read the mercury thermometer.

The electronic thermometer gun is a measurement tool that I personally think has the largest measurement error, but it is the most convenient.

Hope it helps.

I think the traditional glass thermometer is more accurate, because the structure of the electronic thermometer is too complex, and the more complex the process of the machine, the more errors will occur, and the more inaccurate and unstable the result will be. Besides, the glass thermometer is also very useful. It is to throw the mercury column below the 0 scale before measuring, and then put it in the armpit, mouth and other measurement positions, and after about 5 minutes, read and compare it with the standard body temperature of the measurement position you use.

Because of this, we still mainly use glass mercury thermometers to study medicine.

Summary. Hello, how to calibrate the electronic thermometer? You can 1, if it is a thermometer, first take a bowl, pour a small amount of ice and water mixture into it, when the ice is about to melt, insert the thermometer to be corrected into the bowl, read it out after the indication is stable, that is, 0 °C, and then insert the thermometer into the boiling water, read the number, that is, 100 ° The electronic thermometer is generally corrected by laboratory correction using the temperature of the ice-water mixture to 0 degrees Celsius.

If there is an inaccuracy, the specific adjustment method is as follows: You can adjust it by pressing and holding the adjustment key marked with mode.

Short press the SET button twice to enter F2, do the code and let go to enter the F2 parameter trembling, you can press the down button or the up button to switch the Celsius temperature unit and the Fahrenheit temperature unit, and then press the SET button to confirm the unit setting, and the electronic thermometer can be adjusted.

You can try oh dear.

Electric Zen thermometers are generally accurate and reliable, but the accuracy can be affected by some factors. Here are some factors to consider:

1.Brand and quality: Choosing a well-known brand of electronic thermometer with a good reputation can improve accuracy and reliability.

Calibration: Electronic thermometers are calibrated at the factory to ensure the accuracy of measurements. However, prolonged use or improper handling may cause the thermometer to deviate from accuracy, so regular calibration is necessary.

3.How to use: The right way to use it is also important. For example, follow the instructions to properly position the electronic thermometer, making sure to touch the exact area of the object's surface for more accurate temperature measurements.

4.Environmental factors: Ambient temperature, humidity, and other conditions may also have an impact on the accuracy of a thermometer. Especially under extreme temperature or humidity conditions, errors can be caused in the measurement results.
