Hello, Coal Mine. What are the main technical parameters of infrared thermometer? It is also necessary to divide the model, which generally means that 0 to 40 degrees Celsius is the optimal temperature. I don't know what model you're talking about?

Such as working environment, temperature requirements, image-related parameters, functions and displays, automatic warnings, etc. According to the specific needs of the coal mine, see whether the parameters meet the needs.

It is necessary to look at the size of the target and the distance coefficient of the thermometer, the distance from the measurement distance = the minimum diameter of the target * the distance coefficient, and also pay attention to the provisions of the minimum measurement distance.

The infrared thermometer book is the temperature of the surface, but the measurement is to know the emissivity of the measured target, and then set it in the thermometer menu. If the ambient temperature is very high, add an air purge, and a water cooling jacket. If the environment is very bad, use dual wavelength.

The distance coefficient is determined by the ratio of d:s, i.e., the ratio of the distance d between the thermometer probe and the target to the diameter of the target to be measured. If the thermometer has to be installed far away from the target due to environmental conditions, and small targets are to be measured, a thermometer with high optical resolution should be chosen.

The higher the optical resolution, i.e. the higher the d:s ratio, the higher the cost of the thermometer.

The English translation of infrared thermometer is: infrared thermometer

Infrared temperature measurement technology plays an important role in product quality control and monitoring, equipment fault diagnosis and safety protection, and energy saving in the production process. In the past 20 years, the non-contact infrared human body thermometer has developed rapidly in technology, the performance has been continuously improved, the function has been continuously enhanced, the variety has been increasing, and the scope of application has been expanding. Compared with the contact temperature measurement method, infrared temperature measurement has the advantages of fast response time, non-contact, safe use and long service life.

Non-contact infrared thermometers are available in three series: portable, ** and scanning, with a variety of options and computer software, each available in a variety of models and specifications. Among the various models of thermometers of different specifications, it is very important to choose the correct model of infrared thermometer for the user's sleepiness.

Infrared thermometer performance.

In order to obtain accurate temperature readings, the distance between the thermometer and the test target must be within the appropriate range, which is the area of the thermometer's measuring point. The farther you are from the target, the larger the spot size will be. The figure on the right shows the ratio of distance to spot size, or d:

s。On a laser sight type thermometer, the laser spot is above the center of the target and has a bias distance of 12 mm (inches).

Measure distance and spot size.

When setting the measurement distance, make sure that the target diameter is equal to or greater than the size of the spot to be measured. The distance between the "object 1" shown on the right and the gauge is squared because the target is slightly larger than the size of the spot being measured. And "object No. 2" is too far away.

There are roughly 5 models of mine infrared thermometers, namely: CWH425 infrared thermometer, CWH500 infrared thermometer, CWH550 infrared thermometer, CWH700 infrared thermometer, CWH760 infrared thermometer. There is a manufacturer below.

I'll tell you I don't know?
