Shandong Zaozhuang Portable PC-3A (B) laser respirable dust monitor

Portable PC-3A (B) laser respirable dust monitor I. Introduction: Portable PC-3A (B) laser respirable dust monitor is using the latest technologies and materials develop a new generation of intelligent measurement instruments, is assembled with sensors and data processors, this instrument in April 1991 by the Ministry of Health Supervision Division organized an expert review group review, recommended for the National Health Authority public places instrument. This instrument has a test fast, accurate and stable, simple operation, easy maintenance, no noise pollution, AC and DC characteristics. Instrument functions equivalent to similar foreign laser measuring dust levels, lower than the domestic prices of similar instruments. Second, the technical indicators are as follows: 1, respirable particulate matter (PM2.5) 2, measuring range: 0.001 ~ 1mg / m3; 3, the detection sensitivity: 0.001mg / m3; 4, the relative error: ≦ 15%; 5, sampling Time: 2 hours, 5 minutes; 6, the data storage capacity: 0-9 zone, a total of 10 District 500 sets of data; 7, Display: 6 LCD displays eight yards; 8, connected with printer: mini-printer; 9. Power supply: no external power supply with a built-in battery case; there are occasions external power adapter connected to 220V AC power; 10, volume: Host 230mm × 120 mm × 42 mm; 11, Weight: 550g; Third, the specific use of premises: 1 , environmental monitoring stations dedicated dust instrument 2, for the production of industrial and mining labor department dust concentration measurement site 3, epidemic prevention station monitoring public places respirable particulate matter 4, environmental monitoring department of atmospheric particulates environmental testing, survey of pollution sources 5, scientific research, media and other aspects of performance test field test 6. Determination of site dust concentration, dust concentration monitor the exhaust port 7, pharmaceutical manufacturing test 8, 9 occupational health and safety testing, the plant need to clean the air of the place, precision instruments, test equipment, electronic components dust 11, building or place of blasting food, medicine and other manufacturing process management 10, various research institutions, meteorology, public hygiene, industrial labor health engineering, air pollution research testing; site monitoring of workplace exposure 12, indoor air quality testing
