The traditional smoke sampling method is filter tube sampling and laboratory weighing. The technology is relatively mature and widely used in China. In recent years, with the deepening of China's environmental protection and the implementation of the "comprehensive plan for energy conservation and emission reduction", the concentration of particulate matter discharged from pollution sources is getting lower and lower. Some shortcomings and deficiencies of traditional sampling methods are becoming increasingly obvious, such as requiring too long sampling time, weight loss due to filter cartridge damage, residual phenomenon in the sampling nozzle, etc.
Therefore, our company has developed a low concentration smoke sampling gun. The sampling gun can meet the requirements of low concentration (less than 50mg / m3) and high humidity conditions.
