APNA-370

Ambient NOx Monitor

The APNA-370 continuously monitors atmospheric NO, NO2 and NOx concentrations 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.

Division: Ambient
Manufacturing Company: HORIBA, Ltd.
Base product: AP-370 series
  • Continuous NOX, NO, NO2 measurements using a dual cross-flow single chemiluminescence detector and referential calculation.
  • HORIBA original detector (Silicon photodiode sensor) respond to gas concentration quickly .
  • Stable, repeatable measurements; Low range: 0-0.1 ppm F.S.
  • Includes auto-recycle internal drier to make dry air for generating ozone gas
  • Base configuration includes: O3 drier unit, O3 decomposer, reference gas generator and sample pump.
