In wastewater treatment, aeration control, aquaculture, and environmental monitoring, accurate dissolved oxygen (DO) measurement directly impacts process efficiency, energy consumption, and regulatory compliance. Traditional electrochemical DO sensors require electrolyte replacement, frequent calibration, and flow rate control—introducing maintenance burden and measurement uncertainty.
The Instrava Optical Dissolved Oxygen Meter adopts internationally leading fluorescence lifetime technology, based on the physical quenching principle of active fluorescence. Unlike membrane or polarographic methods, this optical solution does not consume oxygen during measurement, eliminating flow rate limitations and significantly reducing maintenance requirements.
With a response time as low as 20 seconds, automatic temperature and pressure compensation, and high mechanical protection (IP68 probe), this system delivers stable, fast, and reliable DO measurement in dynamic industrial environments.
