　　LB-70CtypeHigh flow low concentration smoke and dust testing instrument

　　1、 Execution standards

　　DB37/T2537-2014 "Determination of Low Concentration Particulate Matter in Fixed Pollution Source Exhaust Gas in Shandong Province by Weight Method"

　　HJ/T48-1999 Technical Conditions for Smoke and Dust Samplers

　　JJG680-2007 Smoke and Dust Sampler

　　JJG968-2002 Smoke Analyzer

　　2、 Purpose:

　　Using parallel Pitot tube method for constant velocity sampling, dry wet bulb method for determining the moisture content in the flue, filtration weighing method for determining the mass of particulate matter, and constant potential electrolysis method for determining harmful gases in the flue. Specially suitable for low concentration smoke sampling and testing of harmful gases such as low concentration SO2, widely used in the determination of emission concentration, converted concentration, and total emission of particulate matter and harmful gases from various fixed pollution sources such as boilers, flues, industrial furnaces, etc.

　　3、 Performance characteristics

　　1. One machine is versatile and can measure parameters such as smoke, moisture content, flow rate, dynamic pressure, static pressure, smoke temperature, and smoke gas;

　　2. Configuring a low concentration smoke multifunctional sampling tube can complete the sampling of low concentration particulate matter;

　　3. Automatically store monitoring data, with large data storage capacity, can be printed directly or copied from a USB drive for printing;

　　4. Automatically remember the monitoring parameters entered last time, prioritize use for the next startup, and achieve one click sampling;

　　5. The detachable air-water separator can efficiently dry moisture, filter dust, and effectively protect the sampling pump;

　　6. Adjustable backlight and brightness wide temperature LCD screen, illustrated Chinese menu display, easy to operate;

　　7. The display screen rotates from multiple angles, making it convenient for operators to view data;

　　8. Adopting dual chamber adjustable speed smoke sampling pump and electronic flowmeter, with fast response and high tracking efficiency;

　　9. The flue gas pipeline adopts PTFE pipeline without adsorption, ensuring the accuracy of measurement results;

　　10. Multi level optoelectronic isolation, multi CPU fault-tolerant structure, overcoming electrostatic interference and breakdown;

　　11. Automatically adjust parameters such as temperature and pressure, standard condition data can be directly read out, and there is a power-off protection function. After power on, it automatically enters the pre power-off sampling state;

　　12. Acrylic keys, backlight lighting, clear handwriting, waterproof and dust-proof, wear-resistant and anti-aging, easy to use;

　　13. Password must be entered for instrument maintenance and calibration, and permission management function must be provided to ensure the safety of all instrument parameters;

　　14. Imported electrochemical sensors are used. Integrated design of sensors and signal modules, no calibration required for sensor replacement, with automatic correction function to ensure testing accuracy;

　　15. Fault self checking function, convenient for users to detect, maintain, and use;

　　16. AC/DC dual-use, optional portable AC/DC power supply, can be used in situations without AC power supply;

　　17. The optional smoke gas water separation sampling tube can effectively remove moisture from the flue gas, completely solving the problem of instrument connection pipeline icing and blockage that prevent sampling in low-temperature environments;

　　18. Optional multifunctional oil fume sampling tube and asphalt smoke sampling gun, capable of oil fume sampling and asphalt smoke sampling;

　　19. Equipped with an intelligent flue gas preprocessor, it can filter, heat, dehydrate and process the flue gas in the flue, making the measurement data more accurate;

　　20. Equipped with a multifunctional sampling tube bracket, it can achieve unsupported sampling of various high-altitude perforated flue gas ducts;

　　21. Optional wireless module can achieve wireless remote control testing.
