CLJ-E Laser Dust Particle Counter New Model

CLJ-E Laser Dust Particle Counter New Model

The technical specifications of this series of instruments fully comply with the requirements of the JJF1190-2008 verification regulation issued by the National Metrology Administration. The entire machine utilizes American microcomputer control and processing technology, allowing direct printing of test results. It features multiple functions, high measurement accuracy, fast speed, portability, and simple operation. The instrument can simultaneously measure the number of dust particles of various sizes in a single sampling and allows the selection to observe the number and changes of particles of a specific size, making it highly convenient for researching, testing, and evaluating various clean environments. This series of products has been widely used in cleanroom testing; on-site testing and leak detection of filters; monitoring of ultra-clean workbenches, HVAC systems, computer rooms, medical device production environments, hospital clean operating rooms, automotive spray painting, pharmaceuticals, biochemical products, food hygiene, fine chemicals, precision machinery, aerospace, and other production and research departments. It is an essential instrument for pharmaceutical companies and their regulatory authorities to implement GMP standards, as well as for electronic manufacturing enterprises. The performance design of this series of instruments is advanced, with stable and reliable quality.

CLJ-E Dust Particle Counter New Model uses three-digit digital tubes in the front and eight-digit digital tubes in the back, capable of displaying test data from Class 100 to Class 1,000,000. In contrast, counterfeit versions of our company's product are modified from the 20-year-old CLJ-E, featuring only two-digit digital tubes in the front and six-digit digital tubes in the back, which can only display data up to Class 300,000. They falsely claim to be capable of testing Class 1,000,000, but in reality, they are limited to Class 300,000.
