300G air quality detector used to detect the air quality, with multi function: Particle quality inspection of PM2.5 & PM10, Particle quantity measurement of 0.3um & 2.5um, optional CH2O gas detection. With the function of testing the Temperature and Humidity.

 

Technical Parameter:

1. Particle detector

Channels: PM2.5, PM10

Measuring range: 0~500ug/m3

Sampling principle: light scattering method

Sampling time: 60s

 

2. Particle counter

Channels: 0.3um, 2.5um

Repeatability: Relative standard deviation ≤±10%

Particle size accuracy: Relative error ≤±20%

Light source: with the laser diode
