Three, infrared temperature measurement principle:

Understanding the principle of infrared temperature measurement can help you to use this product correctly, so that the data is more accurate.
1 all objects, solids, liquids, or gases are released to the surrounding environment.
2 the temperature of the object is directly proportional to the intensity of the radiation energy, that is, the higher the temperature, the greater the energy of the radiation.
3 the human body outward radiation energy basic to infrared radiation is not the main.
4 the infrared intensity of the human body to the external radiation and the body\'s own body temperature and body temperature, the body temperature, the higher the temperature, the greater the radiation energy; the lower the ambient temperature, the greater the radiation energy.
5 by measuring the intensity of the infrared energy of the human body to the surrounding radiation, the temperature of the body can be calculated.
6 infrared thermometer itself does not emit any energy to the outside, but passively to perceive the external infrared energy.
7 infrared temperature measuring gun through the precise measurement of the human body to release the weak infrared energy, and then through the complex dynamic calculation and various compensation correction, can accurately measure the body\'s body temperature. The product is composed of a built-in far infrared probe and related hardware and software. It can detect, analyze and record the measured object and environment temperature. Therefore, once the operator product by using methods similar to human specific parts (forehead), and press key and measure the, you can immediately activate infrared radiation receiving sensor, rapidly through the passive infrared sensor probe to due to arterial flow generated heat, to finely measured accurately to the human body temperature.


Four, difficult to answer:

For the following problems encountered in use, please refer to the following guidelines to help solve the problem, if the problem is still not resolved, please call our after-sales service:
1 screen display temperature is greater than 95 degrees
Temperature is in Fahrenheit, the need to turn to the degree Celsius, by pressing the SETTING key to enter the F1, converted to degrees celsius.
2 the screen shows the body temperature mode is lower than 32
The temperature mode is in ldquo; & surface temperature rdquo;; mode, need to turn to & ldquo; body temperature rdquo; & mode by pressing SETING key to enter F3, convert to & ldquo; body temperature & rdquo; mode; &;; mode.
3 screen display HI information
& ldquo; rdquo; & mode, when measured temperature exceeds 42.9 degrees, the product will display HI. Confirm the product in & ldquo; surface temperature & rdquo; or & ldquo; body temperature; rdquo; & mode operation.
In & ldquo; body temperature mode, the human body still shows HI measurement, first check the body of the test site is in contact with the external heat source, if not confirmed, we need to call our after-sales service.
4 screen display LO information
In & ldquo; ldquo; & mode, when the measured temperature is below 32 degrees, the instrument will display LO. & ldquo; & rdquo; & ldquo; &; rdquo; mode of operation. In & ldquo; body temperature rdquo; & mode, the measurement of the human body still shows LO, first according to the following table to find the reasons, if the confirmation is not the cause of the table, you need to call our after-sales service.

Five, body temperature common sense:

The human body is a very complex integrated systems biology, the body temperature is normal life activities of the human body is one of the important data, described below medical temperature measurement of common sense, to help us to keep abreast of their own body key Kang status.

Body temperature
Interpretation: refers to the internal organs of the pulmonary artery, or the real temperature of the esophagus.
Measurement: the use of a dedicated device with a temperature measurement probe into the pulmonary artery or esophagus measurement.
Advantages: precision, constant, the most realistic response to the internal organs of the human body temperature.
Disadvantages: such as intrusive temperature measurement methods, require special equipment and professional technology.

Anal temperature
Interpretation: refers to the temperature of the anal rectum of the human body.
Measurement: a thermometer is inserted into the anus and rectum.
A bit: Anal temperature is relatively stable, close to the body\'s internal temperature, commonly referred to as the medical temperature is the temperature of the anus.
Disadvantages: insert the rectum, is not easy to be accepted, easy to cross infection.

Oral cavity temperature
Interpretation: refers to the body\'s mouth temperature.
Measurement: insert oral tongue with a thermometer under closed temperature.
Advantages: oral temperature is relatively stable, close to the internal body temperature.
Disadvantages: insert the mouth, is not easy to be accepted, easy to cross infection.

Axillary temperature
Explanation: refers to the human armpit temperature.
Measurement: using a thermometer clip in the armpit measurement.
Advantages: the measurement is simple, not easy to cross infection, easy to be accepted, is the most common clinical application of the most common method of measurement.
Disadvantages: than the actual temperature is low, the measurement value of each time will change, the measurement is not accurate enough.

Cochlear temperature
The temperature of the inner ear drum of the human cochlea.
Measurement: a cochlear implant measurement with an infrared ear thermometer.
Advantages: the temperature of the inner membrane of the cochlea is relatively stable, which is close to the internal temperature of the human body.
Disadvantages: must use the infrared temperature measurement method is easily affected by the size and ear cerumen ear canal (commonly known as the influence caused by wax)
Measurement deviation, measured 1~2 times must wait 3-5 minutes before it can be measured again, can not be used continuously, because of contact with ear canal, easy cross infection.

Forehead temperature
Explanation: refers to the human body temperature at the forehead between the eyebrows.
The measurement by forehead temperature measurement instrument.
Advantages: non-contact, fast and accurate.
Disadvantages: to use higher environmental requirements, such as: not in air-conditioning outlet, not in the high temperature environment measurement, the condition itself to be measured is required, such as: forehead there can be no sweat, no hair occlusion.

Comparison of different temperature measurement methods
Different temperature measurement method is used to measure the temperature of the cable, and the difference between the temperature and the temperature can be seen in the following table.

Measuring position

Normal temperature

Anal temperature

36.6 degrees C ~38 C

Oral cavity temperature

35.5 degrees C ~37.5 C

Axillary temperature

34.7 degrees C ~37.3 C

Cochlear temperature

35.8 degrees C ~38 C

Forehead temperature

35.8 degrees C ~37.8 C

Changes in body temperature
Man is a constant temperature animals, body temperature is basically constant, but not static, one day the human body temperature is constantly changing, as follows:

Night is minimum,due to sleep, activity decreases, the body temperature is lowest (below 37 degrees).

Morning is getting high,because go to bed early in the morning from the lower room temperature, muscle contraction, heat generation.

Noon is highest,after the meal, the highest temperature, the body\'s natural sleep regulation, do not want to move.

Three or four pm is gradually low,due to physical exertion, low blood sugar.

At night is minimum,as the sun goes down, the room temperature drops.
