PM2.5 dust monitor, respirable particulate matter analyzers

Measuring range: 0.001 ~ 10 mg / m3 with a 40mm filter sampler and a built-in optical scattering board can be set dust concentrations exceeding the alarm thresholds designed constant current controller and uses laser light to detect PM10, TSP, PM5 and PM2 .5 (standard PM10) Accuracy: ± 10% Repeatability error: ± 2% Measuring time: Standard time is 1 minute (can be arbitrarily set the sampling time). Sensitivity: 0.001mg / m3; cycle store data: 99
