Aerosol Photometer NAP-100 is a precision instrument used to measure aerosol concentration in air streams for HEPA and ULPA filter leak detection and cleanroom validation. It uses light-scattering technology to compare upstream and downstream air quality and identify filtration system leaks in controlled environments.
NAP-100 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 measuring aerosol concentration differences in air streams.
It operates using light-scattering detection:
Air with test aerosol enters sensing chamber
Light interacts with airborne particles
Scattered light is detected by sensors
Signal is converted into concentration readings
Upstream vs downstream values are compared
Quick Answer: It detects particles by measuring light scattered by aerosols in airflow.
Aerosol photometry ensures:
Cleanroom contamination control
HEPA/ULPA filter integrity verification
Compliance with ISO 14644 standards
Safe pharmaceutical and biotech environments
