Q1: What is infrared thermometer?

A1: Infrared thermometer is a temperature measuring instrument based on the principle of infrared rays. This kind of temperature measuring instrument can measure the temperature by the length of infrared rays. Infrared thermometer is a kind of measuring instrument, which can realize short-distance measurement and long-distance measurement, and is a kind of temperature-measuring instrument that can be used in various environments.

Q2: How does infrared thermometer work?

A2: Infrared radiation is the most widespread electromagnetic wave radiation in nature. Objects with a temperature above absolute zero will radiate infrared rays due to their own molecular motion. After the power signal radiated by the object is converted into an electrical signal by the infrared detector, the output signal of the imaging device can completely simulate the spatial distribution of the surface temperature of the scanned object one by one. After being processed by the electronic system, it is transmitted to the display screen and obtained the thermal image corresponding to the heat distribution on the surface of the object.

Q3: What is infrared thermometer used for?

A3: Today, infrared thermal imaging systems have been widely used in fields such as electric power, fire protection, petrochemical and medical treatment. Infrared thermal imaging cameras are playing a pivotal role in the development of the world economy.

Tips: What should we pay attention to when use  infrared thermometer?

1. Determine the temperature measurement range: The temperature measurement range is the most important performance index of the thermometer. Some thermometer products have a range of -50°C to +3000°C, but this cannot be done by one type of infrared thermometer. Each type of thermometer has its own specific temperature range. Therefore, the user's measured temperature range must be considered accurately and comprehensively, neither too narrow nor too wide.
2. Determine target size. Infrared thermometers can be divided into single-color thermometers and two-color thermometers (radiation colorimetric thermometers) according to the principle. For a monochromatic thermometer, when measuring temperature, the area of the target to be measured should fill the field of view of the thermometer. It is recommended that the measured target size exceed 50% of the field of view. If the target size is smaller than the field of view, the background radiation energy will enter the visual and acoustic symbols of the thermometer and interfere with the temperature measurement readings, causing errors.
3. Determining the distance factor (optical resolution). The distance coefficient is determined by the ratio of D:S, that is, the ratio of the distance D between the probe of the thermometer to the target and the diameter of the target to be measured. If the thermometer must be installed far away from the target due to environmental conditions, and a small target must be measured, a thermometer with high optical resolution should be selected. The higher the optical resolution, i.e. increasing the D:S ratio, the higher the cost of the pyrometer.
