Introduction: This laser dust has the international advanced level of the microcomputer, built-in new membrane filter sampler, the continuous monitoring of dust concentration at the same time, can be collected particles, thus can analyze its composition, and the mass concentration conversion coefficient K value. Can direct reading dust mass concentration (mg/m3), PM10, PM5, PM2.5 and TSP cutters for selection. Instruments used powerful pump, to make it more suitable for long sample tube should be equipped with central air conditioning vent PM10 PM10 concentration detection. Technical Parameter 1. 40 mm membrane filter configuration online sampler; 2. With a replaceable cutter PM10 particles, PM5, PM2.5 and TSP to choose from; 3. Direct reading dust mass concentration (mg/m3); 4. A large screen LCD, Chinese characters menu prompt; 5. The detection sensitivity, low sensitivity of 0.01 mg/m3; High sensitivity of 0.001 mg/m3; 6. Repeatability error: + / - 2%; 7. Measuring accuracy: + / - 10%; 8. Measuring range: 0.01 ~ 100 mg/m3; 0.001 ~ 10 mg/m3; 9.
