1. Configure a 40mm filter membrane online sampler.

2 Standard dust cutter, replaceablePM5ThePM2.5ThePM1TheTSPAnd the total dust cutter.

PM10 particulate matter capture characteristics: Da50=10μm±0.5μmand σg=1.5±0.1.

PM2.5 particulate matter capture characteristics: Da50=2.5μm±0.2μmand σg=1.2±0.1.

among whichDa50To improve the capture efficiency50%The aerodynamic diameter of the particulate matter corresponding to the time; σgGeometric standard deviation for capture efficiency.

note1:Correct particles to average particle size0.6μmGeometric standard deviation (σ ≤)1.25Polystyrene particles;

note2:CPMA representation method of relative concentration for the pulse count value per minute.

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