measuring principle Principle
The portable dissolved oxygen meter consists of a main unit and a fluorescent dissolved oxygen sensor. Adopting advanced fluorescence measurement principles, without membranes or electrolytes, requiring minimal maintenance, no oxygen consumption during measurement, and no flow rate/Stirring requirements; And it comes with NTC temperature compensation function, and the measurement results have good repeatability and stability.
Typical applications Application
Widely used in aquaculture, sewage treatment, surface water, industrial and agricultural water supply and drainage, domestic water, boiler water quality, swimming pools, scientific research universities and other industries and fields for on-site portable monitoring of dissolved oxygen in water.
main features Features
