Tell you how to choose an infrared thermometer correctly
Infrared temperature measurement technology has played an important role in product quality control and monitoring, equipment online fault diagnosis, safety protection, and energy conservation. In the past two decades, non-contact infrared thermometers have rapidly developed in technology, continuously improved in performance, and expanded in scope of application. Their market share has been increasing year by year. Compared to contact temperature measurement methods, infrared temperature measurement has the characteristics of fast response time, non-contact, use, and long service life.
Infrared thermometer products include three types: portable, online, and scanning, and are equipped with various options and corresponding computer software. Choosing an infrared thermometer correctly is very important for users. Here, only the thinking steps on how to correctly select a thermometer are proposed for the reference of buyers.
Working principle of infrared thermometer
Understanding the working principle, technical specifications, working environment conditions, operation and maintenance of infrared thermometers is to help users choose and use infrared thermometers correctly.
All objects with temperatures above * * zero are constantly emitting infrared radiation energy into the surrounding space. The infrared radiation characteristics of an object - the size and distribution of radiation energy by wavelength are closely related to its surface temperature. Therefore, by measuring the infrared energy emitted by an object itself, its surface temperature can be accurately measured, which is the objective basis for infrared radiation temperature measurement.
The main factors affecting emissivity
Material type, surface roughness, physicochemical structure, and material thickness
When measuring the temperature of a target using an infrared radiation thermometer, the first step is to measure the infrared radiation of the target within its wavelength range, and then the thermometer calculates the temperature of the measured target. The monochromatic thermometer is proportional to the radiation amount within the band, while the bicolor thermometer is proportional to the radiation amount between the two bands.
