Laser Portable PC-3A continuous respirable dust concentration tester 
 Are using the latest technologies and materials developed by a new generation of intelligent measurement instruments. The instrument consists of hand-held laser respirable dust sensors and handheld processors. The instrument has test speed, high sensitivity, fast response time, stability, light weight, simple operation, the advantages of both AC and DC. Portable PC-3A laser continuous respirable dust concentration tester apply to hotels, theaters, conference  stations, terminals, shopping malls and other public places, respirable dust (PM10) in the automated detection, the concentration of atmospheric dust can be directly observed continuous variation. 

 The specific use of premises: 

 1. For the labor department of industrial and mining production site determination of dust concentration 
 2. Public health and epidemic prevention station monitoring of respirable particulate matter 
 3. Environmental environmental monitoring department of airborne particulate detection, investigation sources 
 4. Municipal monitoring smoke 
 5. Scientific research, media and other aspects of performance test field test 
 6. Field determination of dust concentration, dust concentration monitoring of exhaust 
 7. Pharmaceutical manufacturing test 
 8. Occupational health and safety testing 
 9. The factory where the air needs cleaning, precision instruments, test equipment, electronic components, food, medicine and other manufacturing process management 
 10. A variety of research, meteorology, public health science, industrial labor health engineering, air pollution research 
 11.. Building or place of blasting dust detection; site monitoring of workplace exposure
