| Abstract: | The internal mechanism and working principle of aerosol photometer are introduced. Based on filter membrane sampling method, device of the mass concentration calibration and method of aerosol photometer are proposed. The fogging concentration of aerosol fogging device, whose stability is less than 5%, is verified by experiments. The aerosol photometric mass concentration error is less than ±10%. The traceability of the mass concentration of the aerosol photometer is solved, which can effectively improve the measurement accuracy of the device. |
