PC-3A handheld laser direct-reading dust detector

PC-3A direct-reading laser dust detector presentation: PC-3A direct-reading laser dust detector for the Centers for Disease Control, health surveillance, environmental monitoring and other departments in real-time to quickly measure the air of respirable particulate matter (PM10, PM2.5) concentration The new generation of intelligent measurement instruments. The instrument is portable direct reading light scattering method (PM10, PM2.5) measuring instruments. According to China's health industry standards: - (WS / T 206-2001) designed to "light scattering particles (PM10) Determination of the respirable air in public places." With a test speed, high sensitivity, good stability, light weight, low noise, simple operation, the advantages of AC and DC. Particularly suitable for the measurement occasions without external power supply. PC-3A environmental monitor technical indicators: 1, respirable particulate matter measuring range: 0.001 ~ 10mg / m3 2, cut size: 10 ~ 0.3um; 3, the reproducibility of the measurement instrument error: the average relative standard error of <7% 4, the detection sensitivity: 0.0001mg / m3 5, measurement accuracy: ± 10% (relative correction particles) 6, particulate matter trapping properties: Da50 = (10 ± 0.5) um; δg = 1.5 ± 0.1 7, instruments and weighing method Compare the total uncertainty (ROU) <25% 8, the sampling time: 1 minute 9, the noise: less than 15db 10, Power supply: no external power supply with a built-in battery case; the case with external power adapter connected to 220V AC power. In the case of the built-in battery is fully charged, continuous measurement of five hours 11, volume: Host 230mm × 120 mm × 42 mm 12, Weight: 0.40kg PC-3A direct-reading laser dust detector advantages: 1, real fast measurement of air respirable particulate matter (PM10, PM2.5) concentrations of 2, light scattering portable direct reading (PM10, PM2.5) measuring instrument 3, with a test speed, high sensitivity, good stability, 4, light weight, noise low, simple operation, AC and DC 5, etc., suitable for the occasion measurement without external power supply
