Dissolved Oxygen

Monitoring dissolved oxygen levels is essential for aquaculture, fisheries, environmental water monitoring, and ecological research. Our portable dissolved oxygen meters use galvanic sensors to measure oxygen concentration and saturation directly in the field, with automatic calibration at ambient air by keypress. Waterproof and straightforward to operate, they give you reliable results in freshwater and saltwater applications alike.
