GTI 3991 is a light-scattering linear digital aerosol photometer that subverts the traditional design with advanced technology and scientific design.

After the HEPA filter is put into operation, if there are leaks or gaps due to insufficient installation, the predetermined purification effect will not be achieved, and a leak integrity test must be performed on the high-efficiency filter. Due to the low concentration of atmospheric dust upstream of the tested high-efficiency filter, it is necessary to use an aerosol generator to supplement dust generation to meet the test conditions. Use 3991 aerosol photometer to test the concentration of suspended particulate matter upstream of the high-efficiency filter and conduct a uniform-speed scanning test downstream to know the leak rate of the tested high-efficiency filter, which is convenient for the identification and quantification of leak points, and can be used as a reference for repair.
