Function
 

1) Detection of filtration efficiency 2) Detection of filtration resistance 3) Scan leak detection 4) Can be connected with the      production stream line

Feature
1 ) Horizontal installation of the under test filter, from top to bottom supply air, sampling probe close to the outlet of the filter (≤ 50mm apart), horizontal scanning;
2) Adopting pneumatic way to install and seal the under test filter, simple, fast and reliable;
3) Upstream concentration test configuration bypass valve dilution, dilution rate large, reliable and stable;
4) 4 sets of sampling head, equipped with four large flow of laser particle counter, to achieve a one-time X-ray scan, detection time is short;
5) Intelligent data monitoring system software, scanning detection process directly through the computer LCD display response, data processing, test results automatically print, print paper for single-sided offset paper can be directly attached to the measured filter to achieve
