Brief introduction: Has the international advanced level in the new century new built-in membrane filter sampler microcomputer laser dust, in the continuous monitoring of dust concentration at the same time, can be collected particles, to 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. Features: 1. Design the replaceable particle cutter, implements the PM10, PM5, PM2. 5, the TSP cutter is compatible with a variety of particle separation. 2. Online membrane filter sampler was designed and implemented the continuous monitoring of dust concentration and membrane sampling compatibility, can be analyzed by the composition of the collected particles and the mass concentration of the place conversion coefficient K value. 3. Using a laser light source, mass concentration is not affected by particle color conversion coefficient. 4. The large screen LCD display Chinese characters, Chinese characters menu prompt is realized. 5. The constant current controller is designed to ensure the sampling flow rate constant, the correct cutting curve. 6. Has a built-in optical standard ragtime, ensure that instruments and high stability. 7. Has the special protection of air curtain, to avoid the dust pollution of the core parts of optical system, to ensure equipment reliability. Technical indicators 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. The determination of time: 0.1 minutes, 1 minutes (standard measure time), and (1-9999) 10. Has the public monitoring model, atmospheric environmental monitoring model and labor health model. Can calculate the time weighted average allowable concentration (TWA) and short time contact (STEL), etc.; 11. Save storage: general measurement, cycle can store 99 groups of data. The continuous monitoring, the biggest store 9999 density - through the PC to read; 12. Time sampling, measuring time can be set (1-9999 seconds, shutdown time (0 ~ 9999) seconds, preheating time (0 ~ 10 seconds and sampling number (1-9999); 13. Dust concentration exceeding alarm threshold setting: maximum threshold concentration: 65 mg/m3; Determination of time (1 ~ 9999 seconds; 14. Power supply: Ni - MH rechargeable battery (1.2 V x 4), can be 8 hours of continuous use. With 220 vac / 12 VDC power adapter; 15. Weight: 2.4 kg.
