Sponsor showcase: The technology uses dynamic luminescence quenching to provide fast and accurate readings
HF scientific has expanded its product offering with the addition of the AdvantEDGE series Optical Dissolved Oxygen RDO measurement electrode. Using the principle of dynamic luminescence quenching, the sensor offers reliable accuracy, faster response time and a lower cost of ownership.
Pre-loaded calibration coefficients in the sensor cap simplify setup and eliminate programming errors. Using a design that does not include membranes, the DO electrode reduces maintenance time and allows long deployments without recalibration in demanding environments. The sensor can be used with or without a local display and analyzer.
