SC-L7013 Manual Scanning Test System is designed for manual leak detection of air filters using particle-counting methods. With suitable fixed ducts, the system can be used to scan panel filters and V-bank filters, while special-shaped filters such as cylindrical and triangular filters can also be manually scanned for leakage detection.

During testing, the upstream aerosol concentration is measured first. Based on the entered filter efficiency or preset leakage criterion, the system determines the leakage threshold. The operator then manually scans the downstream filter surface and edges while the particle counter continuously measures downstream particle concentration.
The scanning handle displays the current leakage value and particle count, helping the operator locate potential leakage points during scanning. The SC-L7013 is suitable for both filter production quality control and filter R&D, including leakage inspection, defect localization, and evaluation of manufacturing processes.
