How to purchase a suitable infrared thermometer for oneself
Infrared temperature measurement technology is playing an important role in product quality control and monitoring, equipment online fault diagnosis, safety protection, and energy conservation. In the past twenty years, non-contact infrared thermometers; Infrared temperature detectors 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 advantages such as fast response time, non-contact, safe use, and long service life.
General non-contact infrared radiation temperature measurement products include three categories: portable, online, and scanning, and are equipped with various options and corresponding computer software. Each category also has various models and specifications. The correct selection of infrared thermometer models among different specifications is crucial for users. Here, only the steps to consider how to correctly select the thermometer model are provided for buyers' reference.
The selection of an infrared thermometer can be divided into three aspects:
In terms of performance indicators, such as temperature range, spot size, working wavelength, measurement accuracy, response time, etc; In terms of environment and working conditions, such as environmental temperature, window, display and output, protective accessories, etc; Other options, such as ease of use, maintenance and calibration performance, and price, also have a certain impact on the selection of temperature detectors. With the continuous development of technology, infrared thermometers; The excellent design and new developments of infrared thermometers provide users with various functions and versatile instruments, expanding their choice.
Determining the temperature measurement range is the most important performance indicator of a thermometer. If the product coverage range is -50 ℃ -+3000 ℃, but this cannot be determined by one model of infrared thermometer; Infrared thermometer to complete. Each model of thermometer has its own specific temperature measurement range. Therefore, the user's measured temperature range must be considered accurate and comprehensive, neither too narrow nor too wide. According to the blackbody radiation law, the change in radiation energy caused by temperature in the short wavelength of the spectrum will exceed the change in radiation energy caused by emissivity error. Therefore, it is recommended to choose short wavelength as much as possible for temperature measurement.
