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 the most advanced SMT chip surface mount packaging technology, semiconductor laser sensor technology, and noise proof air pump internationally, and can directly print 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 instruments features advanced performance design, stable and reliable quality
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, biosafety cabinets, HVAC systems, computer rooms, beverage packaging environments, medical device production environments, hospital clean operating rooms, automotive spraying environments, microelectronics, pharmaceuticals, biochemical products, food hygiene, fine chemicals, precision machinery, aerospace and other production and research departments. It is the preferred instrument for pharmaceutical companies and their supervisory management departments to implement GMP standards and for electronic production enterprises.
