According to GB/T 18204.2-2025, instruments used for detecting fine particulate matter in public places must meet relevant technical specifications. If the filter membrane weighing method is used, the instrument should be able to accurately collect particulate matter samples and ensure the accuracy of the filter membrane weighing. The detection instrument using other methods such as laser scattering should also comply with the relevant provisions of the standard for fine particle detection in terms of measurement accuracy, repeatability error, and other indicators to ensure the reliability and comparability of the detection results.

The LD-8 handheld dust concentration detector belongs to the fine particulate matter detector PM2.5 and the inhalable particulate matter detector PM10. It is a portable direct reading measuring instrument that meets the relevant requirements of GB/T 18204.2-2025. It adopts the light scattering method and can quickly and accurately measure PM2.5 and PM10. Its measurement range is 0.001-200mg/m ³, with a detection sensitivity of 0.001mg/m ³ and a relative measurement error of ≤± 10%. It has the advantages of fast testing speed, high sensitivity, and good stability, and is suitable for fine particle monitoring in various scenarios such as environmental monitoring stations, industrial and mining production sites, and public places.
