Product Overview

Use the compact API-454 for in line ozone concentration measurements in percent by weight or g/m3 (specified at time of purchase). The API-454 is an accurate and reliable method of verifying the output of your ozone generator. Multiple ranges are available, allowing precise readings for your particular application. Review the manual here.

Flow rates from 0.5 - 2.0 LPM allow use for many applications. 

Analog Output: 0-5V (Standard) or 4-20 mA (optional) 
Digital Output: RS-232 (Standard) or RS-485 (optional)


  • High range, measure ozone up to 20 % w/w (400 g/Nm3)
  • Proven design for monitoring ozone generator output
  • Outputs allow controls and regulation of ozone production
  • Simple user interface, easy to install
