Product Overview

Teledyne Gas Monitoring

The API-465L UV Photometric Ozone Monitor is perfect for low ozone level measuring, and is extremely stable. It is NIST traceable calibrated and contains pressure and temperature compensation technology to ensure that it reads accurately under any condition. The wall-mount version is in a NEMA enclosure and is extremely hardy. The rack-mount version is a good choice for including in systems. 

The API-465L can be configured to measure any range of ozone up to 500ppm. If you are going to be measuring low concentrations of ozone, it's important to set the sensor to measure lower levels of ozone (i.e. 0-1ppm). 


  • Lower detectable limit of 3 ppb ozone

  • Built-in diagnostics
  • Fast response times
