TH-2000PMb dual channel atmospheric particulate matter concentration monitor

　　working principle:
On the basis of a single channel instrument, a dual channel beta ray method+DHS dynamic compensation system is used to simultaneously monitor PM10 and PM2.5.

　　Instrument features:
◆ Same source sampling: After the sample gas with a total flow rate of 33.34L/min is cut by the PM10 cutter, it is evenly divided into two paths of 16.67L/min through a special splitter. One path directly measures PM10, and the other path is cut by the PM2.5 cutter to measure PM2.5. It can effectively overcome errors between different sampling points.
The instrument input is compatible with both button and touch modes.
The instrument can be extended for monitoring TSP, PM10, PM5, PM2.5, and PM1 (the cutter has testing reports from national authoritative departments).
