Ambient Ozone Monitor

The APOA-370 continuously monitors atmospheric ozone concentrations using a cross-flow modulated ultraviolet absorption method. The APOA-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 continuously monitoring and instantaneously analyzing gases in their unaltered state, has been a preferred method for monitoring atmospheric pollution.
