APNA-370/CU-2

Ambient Ammonia Monitor

APNA-370/CU-2 Ambient Ammonia 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.
