DL-5B portable explosion-proof laser dust detector

1、 Product Introduction

Portable explosion-proof laserDust detectorIt's the new generation that I developed and designedDust concentration detectorThe device can measure the concentration of particles of different sizes in the air in real time and quickly. This instrument complies with the hygiene standards for industrial enterprises (GBZ1-2002), the exposure limit for harmful factors in the workplace (GBZ2-2002), the WS/T206-2001 "Method for determination of inhalable particulate matter (PM10) in the air of public places - light scattering method" standard of the Ministry of Health, the LD98-1996 "Light scattering method for determination of dust concentration in the air" standard of the Ministry of Labor, and the "Hygiene Specification for Central Air Conditioning and Ventilation Systems in Public Places" issued and implemented by the Ministry of Health's Health Supervision Document [2006] No. 58. The instrument achieves real-time monitoring of inhalable particulate matter through the principle of light scattering. By using laser as the light source, the response speed is improved, and the conversion coefficient of mass concentration is not affected by the color of particles, ensuring the accuracy of measurement data.

Portable laser dust detectors can be widely used in disease control centers, health supervision, environmental monitoring, and various manufacturing enterprises to quickly monitor PM2.5, inhalable particulate matter, and total dust in the environment. Suitable for rapid determination of inhalable particulate matter concentration in public places and air conditioning exhaust outlets, as well as for evaluating the purification efficiency of air purifiers.
