The dust counter is our newly develop portable laser dust particles counter which apply semiconductor laser sensor, can be connected to PC data collection system to remote control, so that can directly observe the testing situation, and the testing data can be analysis, processed and saved as Excel document. The technical index can meet the verification regulation JJG547-88 issued by DGS. The counter apply American micro-computer controlling and dealing technology, semi-conductor technology and imported air pump, with the character of multi-function, high precision measure, high speed, portable and easy to operate. The counter one time sampling can test the number of dust particles on different kinds of grain sizes. The counter has been wildly used in cleaning room for electronic manufacturing enterprises, filter for on-site test and leak detection, production and scientific researching departments, such as testing biosafety, HVAC system, computer room, beverage packing environment, medicine, medical instrument production environment, hospital cleaning room, spray environment, micro-electronics, biochemicals, food safety, fine chemical engineering, precision machinery, etc. It is the first choice for HVAC，pharmaceutical enterprise and supervisory department.
