The model 8587A laser photometer uses the same photometer engine that is used in the Automated Filter Tester model 8130A. 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.
Applications
- Respirator certification testing (fit testing)
- Efficiency testing of HEPA filter assemblies
