AP-370 series Air Pollution Monitor Brochure (version G)
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.
