Based on the single channel instrument, the dual channel β - ray method + DHS dynamic compensation system is used to monitor PM10 and PM2.5 simultaneously.
◆ Homologous sampling: the sample gas with a total flow rate of 33.34l/min is cut by PM10 cutter, and then evenly divided into two channels by special shunt
67 L / min, one way was used to measure PM 10 directly, and the other was cut by PM 2.5 cutter, then PM 2.5 was measured. It can effectively overcome different sampling
The error between points.
◆ The instrument input is compatible with both button and touch modes.
◆ The instrument can be extended to monitor TSP, PM 10, PM 5, PM 2.5 and PM 1 (the cutter has the test report of the national authority department).
