The product complies with HJ 653-2021 Technical Requirements and Detection Methods for Continuous Automatic Monitoring Systems for Ambient Air Particulate Matter (PM10 and PM2.5).
Instrument Principle
Based on a single-channel instrument, it adopts dual-path β ray method + DHS dynamic compensation system to simultaneously monitor PM10 and PM2.5.
Instrument Features
• Same-source sampling with total flow of 33.34L/min sample gas is cut by PM10 cutter, then evenly split into two 16.67L/min paths via a special splitter. One path directly measures PM10, the other path measures PM2.5 after cutting by PM2.5 cutter, effectively overcoming errors between different sampling points;
• Instrument input supports both key and touch screen modes simultaneously;
• Instrument can be extended to monitor TSP, PM10, PM5, PM2.5, PM1 (cutters have test reports from national authoritative departments).
