Dust exists in various industries, and the size of the dust concentration has a great impact on the production safety and personal safety of the industry. Therefore, in the overall environment of safe production, industry practitioners have been constantly trying to find ways to achieve dust concentration monitoring, and actively explore research solutions. The traditional monitoring methods in the past are relatively slow. However, with the progress of the times and the improvement of timeliness requirements, the old methods can no longer meet people's needs for a quick understanding of dust concentration. The new type of handheld dust monitors are gradually being widely used in various industries because they can automatically collect and directly display the concentration. 1. The sampling volume of air pump for drainage is usually 1L/min or 2.83L/min. Pump suction sampling has good flow stability and strong back pressure capability. Whether it is in offices, business premises, laboratories, mountains, sea, or aerial work, it is rarely affected by air flow. 2. The detection concentration range is large, usually up to 0.001-20mg/m3 or 0-40mg/m3 (TSP mode). The wide range makes the dust detector sensor almost meet most of the use occasions, such as digital urban management, smart city, Construction sites, garbage dumps, demolition sites, docks, industrial parks, communities, road dust environmental monitoring and monitoring centers. It can also be used for: Quality Supervision Station, Safety Supervision Station, Environmental Protection Bureau, Urban Management Supervision and Law Enforcement Bureau, etc., to compare with the existing dust equipment data on site. 3. The online laser dust concentration detector is a light-scattering dust particle (PM10, PM2.5/or TSP) measuring instrument, which can continuously monitor for 365 days * 24 hours, and the failure rate is extremely low.

Digital Direct Reading Dust Concentration Detector Handheld Dust Monitor is a newly launched three-channel dust detector with CPA certification, TSP, PM10, PM2.5 three particle size can be detected at the same time, can also display Temperature and humidity conditions. It has various functions such as 24-hour continuous monitoring of particle concentration, regular sampling and alarm (early warning) for excessive dust concentration. Mainly applicable to: Quality Supervision Station, Work Safety Supervision Station, Environmental Protection Bureau, Urban Management Supervision and Law Enforcement Bureau, etc., used to compare with the existing dust equipment data on site, continuously compare the changes in dust pollution on site, and provide reliability for law enforcement agencies Valid data parameters.
