The OxyGuard CO2 is the World's first commercially attractive direct dissolved carbon dioxide meter. Previously analytical methods were used, and these methods not only measured dissolved carbon dioxide, but also any acid, base or compound in the water that reacted with the reagents used for the analysis. Now you can simply put the probe in the water and measure. Click on the link for more information.

The OxyGuard R.O. residual ozone analyser is also unique. It uses a combination of modern technology and basic chemistry to give a continuous indication of the residual dissolved ozone content of water. Click here for more information.
