pm25 cutter

Technical characteristics: ▲ TSP sampling inlet its performance to meet the national standard, namely inlet velocity: more than 0.3m / s entrance width and height: b / a = 0.625 ▲ PM10 cutter: da50 = 10.2μm δg = da16 / da50 = da50 / da84 = 1.5 to meet the national standard GB6921-86 in da50 = 10 ± 1μm and requirements for particulates (PM10) sampling of the provisions δg≤1.5. ▲ PM5 cutter: da50 = 4.93μm compared with its trapping efficiency RMRC standard deviation between 0.4-10.7%, to meet the ISO report tolerance of 15% requirement. ▲ PM2.5 cutter: da50 = 2.47μm and "a typical particle size distribution" under "ideal sampler" trap mass concentration predictive value relative deviation of 0.2%. Meet the requirements in the federal standard da50 = 2.5 ± 0.2μm, the ideal sampler trap mass concentration relative deviation ≤10% requirement. With the use of sampling requirements: 1, sample flow rate and accuracy: 100L / min ± 5% 2, sampling filter: Material: fiberglass Dimensions: φ88 3, feeder head size: φ18 × 2
