CLJ-E laser dust particle counter, new model

New CLJ-E Laser Dust Particle Counter
The technical specifications of this series of instruments meet the requirements of the JJF1190-2008 calibration regulations issued by the State Administration of Metrology. The entire machine adopts American microcomputer control processing technology and can directly print the test results. It has the characteristics of multiple functions, high measurement accuracy, fast speed, easy portability, and simple operation. The instrument can simultaneously measure the number of dust particles of multiple sizes in one sampling, and can choose to observe the number and changes of particles of a certain size, which is very convenient for researching, detecting, and evaluating various clean environments. This series of products has been widely used in clean room testing; On site inspection and leak detection of filters; It can monitor ultra clean workbenches, HVAC systems, computer rooms, medical device production environments, hospital clean operating rooms, automotive spraying, 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 supervisory management departments to implement GMP standards and for electronic production enterprises. This series of instruments has advanced performance design, stable and reliable quality
The new CLJ-E dust particle counter adopts a front 3-digit digital tube and a rear 8-bit digital tube display, which can display test data ranging from hundreds to millions. However, the counterfeit of our company's CLJ-E is modified from 20 years ago, with a front two digit digital tube and a rear digital tube consisting of only 6 digits, which can only display data up to 300000 levels. Falsely claiming to be able to test at the million level, in reality it is at the 300000 level.
