Description

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.
