The body's temperature is relatively constant, with a slight fluctuation within a normal range of no more than 1 degree over a 24-hour period. Physiologically, body temperature tends to be slightly lower in the morning and slightly higher in the afternoon. Physical activity, after eating, and before or during menstruation or pregnancy can lead to slightly higher body temperatures, while older individuals tend to have lower temperatures. A temperature above the normal range is considered a fever, with 37.5-38 degrees considered low-grade fever, 38-39 degrees moderate fever, 39-40 degrees high fever, and temperatures above 40 degrees considered hyperpyrexia. The relative constancy of body temperature is an important condition for maintaining normal life activities. Temperatures above 41 degrees or below 25 degrees can seriously affect the function of various systems, especially the nervous system, and even pose a threat to life. The production of heat and heat dissipation are regulated by the nervous center, and many diseases can disrupt the normal regulation of body temperature. Clinically, checking a patient's temperature is important for diagnosing diseases or judging the prognosis of certain diseases.

【商品介绍】
This product features rapid display of readings, beeping sound alerts, high precision, temperature alarm for high and low temperatures, energy-saving, memory storage, and automatic shutdown.
The working voltage is 1.5V. It uses high-precision sensors and microcomputer technology to quickly, accurately, and conveniently measure human body temperature. The shell is made of non-toxic plastic imported from Japan, avoiding the problems of traditional mercury thermometers, such as easy breakage, mercury pollution of the environment, and difficulty in reading. This electronic thermometer is safe and practical, no longer worrying about the adverse consequences of mercury poisoning caused by glass breakage when using traditional thermometers by children. Moreover, it can accurately test body temperature within a very short time, making it a must-have item for the home. The measurement accuracy reaches 0.1 degrees, with sound prompts and memory function. It can be used for oral, axilla, and rectal measurements.

【Usage Method】
1. Before use, it is necessary to disinfect the thermometer sensor head and the temperature measuring rod with cotton soaked in alcohol.
Press the power button, and the beeper will make a beeping sound. The display will show the prompt symbol for about 2 seconds, then show the last measured temperature for about 2 seconds, and then show L°C, where 'C' flashes, indicating that it is ready to measure.
3, insert the thermometer sensor into the measurement site, and the display will show the temperature gradually rising. Meanwhile, the °C symbol will flash, indicating that the measurement is in progress. If the temperature remains the same for 16 seconds during the measurement, the °C symbol will stop flashing, indicating that the temperature measurement is complete and the result has been remembered. You can then read the displayed temperature value.
4, If the temperature is greater than 37.5°C, you will hear a short, rapid beep sound: Bi-Bi-Bi-Bi (beep every 0.125 seconds), indicating that the measurement is complete and suggesting that you have a fever. If the temperature is less than or equal to 37.5°C, you will hear a slower sound: Bi-Bi-Bi-Bi (beep every 0.5 seconds), indicating that the measurement is complete and that your temperature is normal.

5, if the measured temperature is less than 32.0℃, then display L℃; if it is greater than 42.0℃, then display H℃.

6, After the measurement is completed, if the power key is not pressed to turn off the power, the device will automatically turn off after 10 minutes.

Electronic thermometers are powered by microcomputer technology to provide users with fast, accurate, and convenient temperature measurement. The shell is made of plastic materials, avoiding the problems of traditional mercury thermometers, such as easy breakage, mercury pollution, and difficulty in reading. They are equipped with LCD displays.

Simple Usage Instructions: (With Instruction Manual):

The digital display shows the temperature clearly and is easy to read. The measuring range is 32-42°C, with an accuracy of ±0.1°C.

【Lock Function】：

With an automatic memory function, it remembers the final temperature test results. Low power consumption, each battery can last for two years. Especially, the electronic thermometer does not contain mercury, which is safe for both the user and the surrounding environment. It can be used directly in the mouth for temperature measurement, making it particularly suitable for use in family, hospital, and other settings. Display method: LCD display.

【Product Features】:

The measurement is precise and fast; it is convenient to read, unlike general thermometers that require looking at scales from left to right. The electronic digital thermometer uses digital display to tell you the temperature directly.

【Measurement Reminder】:

Measure the temperature and you will hear a sound reminder. Unlike ordinary thermometers, if you take it too early, you might not have measured it correctly, and if you take it too late, it will delay your time.

【Memory Function】：

The temperature readout will be remembered in the thermometer until the next measurement.

Battery Replacement:

1. When the display does not show any numbers, it means the battery is low on power and must be replaced as soon as possible to ensure the accuracy of the measurement.

2. When replacing the battery, turn the thermometer's display screen down, pull out the battery cover, and gently pull out the thermometer mechanism about 5-15mm (do not apply excessive force or pull too far, to avoid damaging the components). Remove the old battery, insert a new battery with the negative pole facing up, push the mechanism back into place, and replace the battery cover.

【注意事项】：

Electronic thermometers are precision electronic products, so please note:

1. Do not drop or twist the body from a high place.

2. The temperature sensor to the front of the display screen can be disinfected with alcohol, but the screen and the parts after it, as there is no waterproof device, can only be wiped with a dry cloth. It must not be placed in water or boiled in hot water for disinfection.

3. Do not open any parts except for replacing the battery.

4. Do not place in high temperatures or direct sunlight, and do not touch any corrosive substances to prevent chemical changes in the components that could affect the operation of the device.

Please properly dispose of spent batteries to avoid polluting the environment and water sources.
