Light scattering microcomputer laser dust analyzer

TC-PM21 typeLight scattering microcomputer laser dust analyzer

Product Parameters

1. Equipped with a lifting protection system, it can detect concentration and collect dust samples at the same time.

2. Can detect PM10, PM5, PM2.5, PM1, TSP, and total dust

PM10 particulate matter capture characteristics Da50=10 μ m ± 0.5 μ m, б=1.5 ± 0.1

The capture characteristics of PM2.5 particulate matter are Da50=2.5 μ m ± 0.2 μ m and б=1.2 ± 0.1.

Da50 is the aerodynamic diameter of particulate matter corresponding to a capture efficiency of 50%; σ g is the geometric standard deviation of capture efficiency.

Note 1: The corrected particles are polystyrene particles with an average particle size of 0.6 μ m and a geometric standard deviation of б ≤ 1.25;

Note 2: CPM is a method of expressing relative concentration by counting pulses per minute

3. LCD display direct reading of dust mass concentration (mg/m3)

4. Measurement sensitivity: For calibration particles, the instrument counts 1CPM=0.001mg/m3;

5. Repetitive error: ± 2%;

6. Relative measurement error: For calibrated particles, the relative measurement error is less than ± 10%;

7. Measurement range: 0.001-100 mg/m3

8. Equipped with the function of eliminating humidity interference (humidity correction), it can be used under conditions of high relative humidity (>50%) in the environment.

9. Equipped with a powerful suction pump, it can reduce the impact of air velocity on measurement results.

10. Measurement time: Standard time is 1 minute, and the sampling time can be set according to customer requirements.

11. Measurement mode: general measurement, continuous monitoring, labor hygiene.
