First, the instrument uses:
       ZY-CLJ-E laser dust particle counter is a counting device used to detect the number of dust particles contained in a unit volume in a purified environment. All indicators are calibrated according to the JJF 1190-2008 dust particle counter calibration specification issued by the General Administration of Quality Supervision, Inspection and Quarantine. The whole machine function is controlled by microcomputer, and the test results can be printed directly. This instrument is compact in design, has many functions, high test accuracy, fast speed, easy to carry and use. It is very convenient for researching, detecting and evaluating various clean environments. The instrument also has a purification level alarm function, which can be used to monitor the cleanliness of clean rooms. Therefore, the instrument can be widely used in microelectronics, medical pharmacy, biochemical products, blood products, food hygiene, cosmetics, precision machinery, fine chemicals and aerospace and other departments.
