Laser Photometer 8587A

Request A Quote Related Products


Stand-alone photometers are used for custom made test chambers, e.g. in respirator certification testing, and for respirator design and development. Light scatter photometers are the preferred choice for detectors in respiratory testing due to their very high dynamic range and sensitivity. With the need for respiratory masks with higher protection factors as well as the measurement equipment improved, Laser Photometer Model 8587A is the result of such continued improvement of the measurement capabilities.

Product Details

The model 8587A laser photometer uses the same photometer engine that is used in the Automated Filter Tester models 8130 and 8127. It uses a 30 mW laser to illuminate and collect the scattered light from airborne particles. An internal valve allows switching between upstream and downstream sampling. Due to its portability and wide dynamic range, it also is used in HEPA filter scanning systems measuring the penetration efficiencies of large, high-efficiency filter assemblies. 

Features and Benefits
