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.

    APNA-370

    The APNA-370 continuously monitors atmospheric NO, NO2 and NOxconcentrations using a cross-flow modulated semi decompression chemiluminescence method. The APNA-370 employs an independent, internal dry-method sampling device to achieve the highest levels of sensitivity and accuracy. The dry method, due to its minimal maintenance requirements and capability of continuous monitoring and instantaneous analysis of gas in its unaltered state, has been a preferred method for monitoring the atmospheric pollution.
