Dust particle counter is mainly used to test what
CLJ-E type (semiconductor laser) dust particle counter (LED display)
The technical indicators of this series of instruments meet the requirements of the JJF1190-2008 verification regulations promulgated by the State Administration of Metrology. The whole machine functions adopt American micro-computer control processing technology and internationally advanced SMT chip chip packaging technology and semiconductor laser sensor technology and anti-noise air pump. The test results can be printed directly. It has many functions, high measurement accuracy, fast speed, easy to carry and easy to operate. The instrument can simultaneously measure the number of dust particles of various particle sizes at one time, and can choose to observe the number of particles of a certain particle size and its changes, which is very convenient for researching, testing and evaluating various clean environments. This series of instruments has advanced performance design and stable and reliable quality.
This series of products has been widely used in clean room testing; filter on-site inspection, leak detection; can monitor ultra-clean workbench, biosafety cabinet, HVAC system, computer room, beverage packaging environment, medical device production environment, hospital clean operating room, Automotive spraying environment Microelectronics, pharmaceutical, biochemical products, food hygiene, fine chemicals, precision machinery and aerospace production and scientific research departments, is the pharmaceutical companies and their supervision and management departments to implement GMP standards and electronic production enterprises.
