Laser Photometer

8587A - TSI Inc.

The photometer owners asked TSI to develop a modern version of the Laser Photometer 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
