APNA-370/CU-2

Ambient Ammonium Monitor

APNA-370/CU-2 Ambient Ammonium Monitor measures increased nitrogen oxide (NOx) raected through oxide catalyst treatment as Ammonia (NH3) concentration with chemiluminescent (CLD) method. HORIBA's original Cross-flow modulation method ensures long-term stability and reliable measuring value with 5ppb for min. detectable sensitivity.

 

Division: Ambient
Manufacturing Company: HORIBA, Ltd.
Base product: AP-370 series
  • Contiuous monitoring for Ammonia in ambient air with high sensitivity.
