Product Overview<\/b><\/strong><\/h3>\n

The asphalt fume sampling probe is designed for collecting asphalt fumes from fixed pollution source flues. Equipped with an S-shaped Pitot tube, heating, and cooling functions, it enables accurate measurement of asphalt fume concentration and emissions.<\/p>\n

The device complies with the HJ\/T 45-1999 \u201cDetermination of Asphalt Fumes in Flue Gas from Stationary Sources by Gravimetric Method\u201d<\/strong>\u00a0standard and is used in conjunction with dust and gas testing instruments to achieve precise sampling, supporting environmental monitoring and emission control.<\/p>\n

Working Principle<\/b><\/strong><\/h3>\n

The S-shaped Pitot tube accurately guides asphalt fume gas into the sampling tube. The tube is automatically heated to 42\u202f\u00b1\u202f10\u202f\u00b0C to prevent condensation, ensuring continuous sampling. When the flue gas temperature reaches \u2265150\u202f\u00b0C, the cooling system is activated, using ice to lower the temperature and maintain stable operation. Asphalt fumes are collected on a constant-weight glass fiber filter, and concentration is determined by filter weight increase for quantitative analysis.<\/p>\n

Key Features<\/b><\/strong><\/h3>\n
    \n

      The Asphalt Fume Sampling Gun is a specialized instrument designed for collecting asphalt fume emissions from stationary pollution sources such as asphalt plants, paving operations, and industrial exhaust systems. Constructed with corrosion\u2011resistant materials and precise flow control, the gun ensures accurate sampling of asphalt fumes, including volatile organic compounds (VOCs) and particulate matter, under high\u2011temperature and chemically aggressive conditions. Optional heating modules prevent condensation, while its ergonomic design and secure connections make it reliable for field use. This equipment is widely applied in environmental monitoring, occupational health studies, regulatory compliance testing, and industrial emission assessment.<\/p>\n
