PMS 20
Four-channel particle size monitoring
Simultaneous monitoring of PM1, PM2.5, PM10, TSP particulate mass concentration with adjustable sampling time.
Pump-type high-efficiency sampling
2.83L/min brushless vacuum pump, strong power is not easy to accumulate dust; large flow rate is more stable, more accurate measurement of particles of various sizes.
Sheath gas filtration
Built-in sheath gas and multi-channel filtration structure for up to 20,000+ hours of operation.
Calibration Zero
Zeroing, calibration, and other functions are optional for easy operation and more secure measurements.
Precision calibration
The factory calibration is aligned to the β-ray method, effectively reducing secondary calibration costs.
