Test method for equipment in test chamber of particulate matter purifier

Before the test of the particulate matter purifier test chamber, the equipment for pollutant generation, measurement and recording should be in normal use. The performance, uncertainty, and range of test instruments and meters should meet the following measurement requirements:

1.Particle mass concentration tester:the uncertainty should be within ±0.001mg/m³;

2.Gaseous pollutant mass concentration tester:the uncertainty should be within ±0.01mg/m³;

3.Ozone analyzer:the uncertainty should be within ±0.1ppb;

4.Dust analyzer:the uncertainty should be ±0.001mg/m³;

5.Biochemical incubator:temperature control accuracy ±1℃;

6.Refrigerator:temperature control accuracy 5℃~10℃；

7.Pressure steam sterilizer:the uncertainty should be within ±0.30；

8.Oil mist generator:single nozzle sprayer with an average particle size of 0.8μm;

9. Aerosol generator: It is polydisperse solid phase potassium chloride (KCl) particles with a particle size range of 0.3-10.0μm.
