High-precision infrared non-contact industrial temperature measuring gun
Industrial general-purpose medical temperature measuring guns are used in areas where infectious diseases occur, and use far-infrared rays to emit light signals to measure the temperature of the human body without touching the human body. It has special uses during the SARS period and the bird flu period. The temperature is designed to be -50 to 480°C, and the low temperature measurement of minus 50°C can be easily realized, and it can also be used normally in areas with low temperatures such as northeast and northwest.
What is the principle of infrared thermometer (temperature gun)?
The scientific name of the temperature measuring gun is "infrared thermometer" or "infrared radiation thermometer". The principle of the temperature measuring gun is to passively absorb the infrared radiation energy of the object to obtain the temperature value of the object
Your body is always emitting energy outward, and a thermometer works by receiving radiant energy from an area of your body. Infrared temperature guns can only receive electromagnetic waves of various waves, but cannot conduct heat directly. The most important of these is the mention of the law of black body radiation during the conversion process from "electromagnetic wave information" to "temperature information".
What is the principle of the temperature gun?
1. The principle of the temperature measuring gun is: the infrared temperature measuring gun is composed of an optical system, a photoelectric detector, a signal amplifier, signal processing, and display output.
2. The optical system gathers the infrared radiation energy of the target in its field of view, and the size of the field of view is determined by the optical parts of the thermometer and its orientation. When using an infrared radiation thermometer to measure the temperature of the target, it is first necessary to measure the infrared radiation of the target in its band range, and then the temperature of the measured target is calculated by the thermometer.
Classification of temperature measurement
1. Human body temperature measurement: accurately measure human body temperature, replacing traditional mercury thermometers.
2. Skin temperature measurement: measure the surface temperature of human skin, such as medical skin surface temperature measurement.
3. Object temperature measurement: measure the surface temperature of an object, for example, it can be used to measure the temperature of the surface of a teacup.
4. Liquid temperature measurement: measure the temperature of the liquid, such as the temperature of the baby's bath water, the temperature of the milk in the bottle, etc.
