There are generally two places where dust concentration detectors are used. One is to measure the dust content in the environment and flue, which is mainly related to environmental protection and occupational health. The other is to prevent dust explosions, which is mainly used in production workshops. At present, the most advanced dust detection technology is the laser scattering method.
The following is a comparison table of several detection technologies:

TSI provides measurement problem research, confirmation and solution services to customers around the world. As a leading company in the design and production of precision measuring instruments, TSI works with various research institutions and customers around the world to develop standards for measuring instruments in many disciplines.< br/>TSI's aerosol (dust) monitor has a wide range of measurement, suitable for measurements from offices, workplaces to outdoor environments, construction sites and other occasions. It can simultaneously measure the mass concentration distribution of 5 different particle size segments, corresponding to PM1, PM2.5, inhalable particulate matter PM4, PM10 and total PM (<15um), providing fast and accurate measurement results.
TSI aerosol (dust) monitor uses the principle of 90-degree right-angle light scattering, uses an air pump to suck aerosol particles into the optical chamber, and then measures the concentration of particles by the amount of light scattered. The special " ;sheath gas" protection design in the air path allows dirty air to be wrapped, so when the particles enter the optical chamber, the optical lens can still remain clean for more accurate readings and less maintenance.
