APNA-370/CU-2 Ambient Ammonium Monitor

Overview

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.

Features

    • Contiuous monitoring for Ammonia in ambient air with high sensitivity.

Manufactured by HORIBA
