Description

Portable LED Display Laser Dust Particle Counter With Printing Function
Description:
The counter' technical index meet the national verification regulation JJG547-88 issued, It features  microcomputer control by the United States deal with the most advanced international SMT SMD chip packaging technology and semiconductor laser sensor technology and anti-noise pump, test results can be printed directly. A sampling instrument can simultaneously measured multiple particle size dust particles, and can choose the number and the changes observed in which a particle diameter, are very convenient for research, testing and evaluation of a clean environment.
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.
