This Automated Filter Tester, an Oil aerosol tester, can quickly and accurately measure the filtration efficiency of filtration protection equipment and material. The Automated filter tester designed to meet the global commercial respirator standards, durability, reliability and low maintenance frequency , which could meet the harsh requirements of manufacturing and quality control environment. Specially designed aerosol generators and detectors enable highly reproducible and reproducible filter efficiency testing.  Beyond that, the model 8127 have a highly automated and self-diagnostic system that greatly simplifies operation/ increases productivity and improves overall measurement performance.
 
Operations
 The filter placed in the middle of the filter fixture, press the start double switch to start testing.
Cylinder quickly descends the upper end of  the filter fixture, the aerosol passes through the filter.
Two optic-scattering photometer simultaneously measure the aerosol concentration level upstream and downstream of the filter to calculate the particle penetration value.
High-precision electronic pressure transducers determine resistance and flow rate.
The pressure and photometer readings determine zero compensation and background values.
 
Features Benefits
Compliance with various respirator regulations. Simple Fast and automated Operation.
The test results are highly consistent.
The warrant is designed to manufacture the environment.
Service and Support
