As diet industry lampblack pollution has become the major urban environmental pollution problems

real-time monitoring technology of lampblack is used in the environmental protection department increasingly.The current TGS2100 gas detector based on the real-time monitoring technology has many deficiencies such as low detection precision.In order to improve the precision and efficiency of lampblack detecting

the non-dispersive infrared（NDIR）method is innovationally used in the gaseous state absorbing cell to solve this problem.The idea is to use a broadband light source and the pyroelectric detector with the absorption wavelength of 3.4 μm to measure the lampblack concentration.At the same time

relevant data is sent to the terminal.
