PM350 Aerosol Photometer

PM-350 aerosol photometer is used for on-site leakage detection after the installation of the efficient filter and its system, mainly to check small pinholes and other damage in the filter, such as frame sealing, gasket seal and leakage on the filter frame.The purpose of leakage detection is to check the sealing of the efficient filter and the connection part with the installation frame, timely find the defects in the installation, and take corresponding remedial measures to ensure the cleanliness of the area. We can support OEM/ODM service.


PM-350 Aerosol Photometer 
The PM-350 can automatically switch the upstream and downstream aerosol concentration to determine the filter for leakage. The portable scanning probe enables the operator to quickly and accurately identify the leakage points in remote locations and determine other leakage ratios, and when the alarm line is exceeded, the display board displays an alarm.
