1. Product Overview Guorui Liheng Environmental Protection Sulfuric Acid Fog/Hydrogen Fluoride Sampling Tube All-in-One Sampling Gun GR8028 Sulfuric Acid Mist//Hydrogen Fluoride Sampling Tube is a sampling equipment carefully designed by our company for on-site sulfuric acid mist or hydrogen fluoride sampling. It has the characteristics of integrated full-process heating bong, high-precision temperature control host, high-efficiency insulation box, and adaptation to various absorption bottles. With the smoke sampler, it can be used for both horizontal and vertical flue sampling. It is easy to operate and carry, and is an on-site sulfuric acid mist//hydrogen fluoride sampling instrument. 2. Scope of application The smoke and dust sampler is suitable for sampling sulfuric acid mist, hydrogen fluoride, which are fixed pollution sources. It can be used by environmental protection, health, labor, security, scientific research, education and other departments. 3. Technical features 1) Integrated full-process heating bong, using high-corrosion titanium alloy material, beautiful appearance. 2) The sampling tube is lined with polytetrafluoroethylene pipe to avoid pipeline adsorption. 3) One gun and three uses can meet the sampling of granular, steam and gaseous sulfuric acid mist. It is also suitable for sampling hydrochloric acid mist and hydrogen fluoride. 4) The filter membrane clip is made of PTFE, which automatically maintains a constant temperature of 120℃ during sampling. 5) Equipped with pipeline closing device, convenient to close the air line. 6) High-efficiency insulation box, which can be placed in a variety of absorbent bottle combinations. 7) Can be used for both horizontal and vertical flue sampling. 8) Low voltage DC power supply, safe and reliable to use. 9) Imported high-precision thermostat, high-power power supply, fast heating to constant temperature. 10) Multi-functional combined sampling gun, including smoke temperature and pitot tube flow rate measurement functions. 4.
