Product Details

In 1990, began developing an advanced-technology light scattering photometer to replace aging instruments incapable of measuring the high protection factors provided by newer gas mask designs. The result was the Laser Photometer Model 8587A, which is still in service for testing filter efficiency.

The  photometer owners asked TSI to develop a modern version of the Laser Photometer Model 8587 that retains data continuity with the original version. Without data continuity, vast amounts of legacy research would not be directly comparable to new research. The result was the Laser Photometer 8587A.

The Model 8587A can also be used in HEPA filter scanning systems to measure the penetration efficiencies of large, high-efficiency filter assemblies.
