It is used in medical,electronics,precision machinery.

This handheld dust quick detector is the special detecting instrument used to measure the value of PM2.5 (repairable particles) and PM10 (inhalable particle) in the air. It is a high-tech product developed independently and integrating gas dynamics, digital signal processing and optical-mechanical-electrical integration on the basis of absorbing oversea advanced high sensitivity micro laser sensor technology. The device is characterized by high test precision, stable performance, strong multiple functions and easy and convenient operation and can be used widely for determination of indoor and outdoor public environment and atmospheric environment, PM2.5 air quality detection and PM2.5 dust particle amount.
