Dual wavelength pyrometer technology is playing an important role in product quality control and monitoring, equipment online fault diagnosis, safety protection and energy saving. In the past two decades, dual-wavelength pyrometers have developed rapidly in technology, their performance has been continuously improved, their scope of application has been continuously expanded, and their market share has increased year by year. Compared with the contact temperature measurement method, the dual wavelength pyrometer has the advantages of fast response time, non-contact, safe use and long service life.

Dual-wavelength pyrometer products include three series: portable, online and scanning. According to different use conditions, various optional accessories and corresponding computer software are required to be used together. There are various models and specifications in each series. Among various types of thermometers with different specifications, it is very important for users to choose the correct infrared thermometer model.
