OxySense - Dissolved Oxygen Meter




The OxySense range of online DO meters utilizes the very latest and best optical DO sensor available in the world today. It is an optical luminescent device which is extremely resistant to abrasion, extremely stable, and has greatly reduced maintenance and whole life costs.


The OxySense Optical Dissolved Oxygen Meter with self-cleaning and self-verification offers enhanced reliability and unrivaled low maintenance. Optical DO meters have largely replaced electrochemical DO sensors due to their better reliability and lower maintenance requirements.
