APNA-360/CU-2 Ambient Ammonium Monitor
Overview
APNA-360/CU-2 Ambient air pollution Ammoniua monitor measures increased nitrogen oxide (NOx) reacted through oxide catalyst treatment as Ammonia (NH3) concentration with chemiluminescent (CLD) method. HORIBA original Cross-flow modulation method ensures long-term stability and reliable measuring value with 10 ppb for min. detectable sensitivity.
Features
- Continous monitoring for Ammonia in ambient air with high sensitivity.
Manufactured by HORIBA
