Use method of infrared temperature measuring gun
Infrared temperature measuring gun, also known as infrared thermometer, can accurately measure the temperature of the human body within 1 second. When using, just aim the probe at your forehead and press the button. The working principle is actually very simple: when the temperature of the object is higher than "absolute zero", that is, - 273 ℃, the object will radiate infrared rays. Use the infrared probe to obtain the infrared light intensity of different objects. After the amplification circuit and analog-to-digital conversion circuit, the temperature data can be displayed on the LCD.
Use method of infrared temperature measuring gun
1. When using the non-contact infrared temperature measuring gun to measure the temperature, point the non-contact infrared temperature measuring gun at the measured object and press the key. At this time, pay attention to the ratio between the distance and the size of the measuring area. The machine is equipped with a laser lamp for aiming at the measured object.
2. Object distance ratio (D: S)
It refers to the ratio between the measured distance and the surface area of the measured object. When the distance between the non-contact infrared thermometer gun and the measured object increases, the surface area of the thermometer and the measured object is required to be larger. D:S=12:1
3. Observation range
Make sure that the measured target is larger than the measurement area of the machine. The minimum diameter of the tested area should be more than 1.5 square centimeters.
4. Reflectivity
The emissivity of most organic materials, paints or oxidizing materials is 0.95 (already set in the machine). Smooth or polished metal surfaces may lead to inaccurate measurement values. When compensating, it is necessary to cover the surface with tape or black paint, and wait until the temperature is the same as that of the following materials, and then conduct temperature measurement.
5. Press the battery switch, install the battery correctly, press the switch button to start the machine, the LCD displays the battery symbol, temperature value, and the value retention time is about 7 seconds.
6. Use
According to the size of the measured object, select the appropriate distance, aim at the measured object, press the button switch, and the LCD will display the temperature value and reading.
