Aerosol Photometer NAP-101 is a precision instrument used to measure aerosol concentration in air streams for HEPA and ULPA filter leak detection and cleanroom validation using light-scattering technology.
It is used to:
Detect HEPA/ULPA filter leaks
Measure aerosol concentration in airflow
Compare upstream vs downstream air quality
Validate cleanroom filtration systems
Support HVAC certification testing
Quick Answer: It detects filter leaks by comparing aerosol concentration before and after filtration.
It works using light-scattering detection:
Air enters optical chamber
Aerosol particles scatter light
Detector captures scattered light
Signal is converted into concentration reading
Upstream and downstream values are compared
Quick Answer: It detects particles by measuring how they scatter light inside an optical chamber.
It ensures:
Cleanroom contamination control
Filter integrity verification
ISO 14644 compliance
Safe pharmaceutical and biotech environments
Quick Answer: It verifies that air filtration systems are leak-free.
Pharmaceutical cleanrooms
Biotechnology labs
Semiconductor facilities
Healthcare HVAC systems
Food processing clean zones
Filter certification labs
Use it when:
Performing HEPA/ULPA leak testing
Validating cleanrooms
Checking HVAC filtration systems
Ensuring contamination control compliance
Do NOT use it when: Particle sizing or classification is required (use a particle counter instead)
Yes. It detects leaks by identifying differences between upstream and downstream aerosol concentrations.
