APOA-370

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 the atmospheric pollution.

 

 

Division: Ambient
Manufacturing Company: HORIBA, Ltd.
Base product: AP-370 Series

• Cross-flow modulated ultra-violet absorption detector; Low range: 0-0.1 ppm F.S.
• Heated de-ozonizer removes any O3 in the reference gas to:
- Reduce interference
- Eliminate moisture interference
- Prolong life-cycle of the UV lamp
• Only inert materials (glass or PTFE) contact sample.
