The dust mass concentration detection methods are:

q Air sampling pump sampling (active sampling, weighing method)

q Light scattering analysis method (optical measurement, direct reading)

q Conical electrode oscillating microbalance analysis method (TEOM, direct reading)

q Beta ray attenuation analysis method (BAM, direct reading)

q Piezoelectric microbalance method (Piezobalance)

q Diffusion sampling (passive sampling, weighing method)

q Cascade multi-stage sampling (impact, weighing or counting method)

Today we introduce the laser dust monitor in detail. Laser dust monitors are widely used in disease prevention and control centers, centralized air conditioning and ventilation system detection, air purifier purification efficiency evaluation, mining, metallurgy, power plants, chemical manufacturing, health supervision, environmental protection, environmental online monitoring, etc.

The types of laser dust monitors are divided into:microcomputer laser dust monitors, multi-functional laser dust monitors, continuous monitoring laser dust monitors, explosion-proof laser dust monitors, etc.

Detection principle of laser dust monitor: When the light beam irradiates the particles, it will cause light scattering and absorption. By measuring the intensity of the scattered light, the dust mass concentration is obtained through conversion.

Advantages of Laser Dust Monitor:

üIndoor PM2.5 detection method approved by relevant national standards such as the Ministry of Health, Ministry of Housing and Urban-Rural Development, and the Safety Supervision Bureau.

üThe instrument is small and easy to carry.

üEasy to use and fast detection.

üContinuous monitoring of particle/dust mass concentration is possible.

üDirectly read the concentration value on site

(real-time concentration, average concentration, TWA, STEL).

üCheap price, less consumables, low maintenance cost.

Disadvantages of laser dust monitor:

v The result is related to the particle size and color component and needs to be calibrated.
