Product Overview

SURE3000 dissolved oxygen meter is a precision instrument mainly used to measure the oxygen content of solution media. Due to the close relationship between the temperature of the medium and the dissolved oxygen value, the instrument needs to be equipped with a temperature compensation unit for compensation. The dissolved oxygen meter has the characteristics of accurate measurement, reliable operation, simple operation, low maintenance, and compact structure. Widely used in industries, agriculture, scientific research, environmental protection, and other fields. The oxygen sensitive film of the dissolved oxygen electrode consists of two metal electrodes in contact with the supporting electrolyte and a selective film. Thin films can only pass through oxygen and other gases, and cannot pass through water and soluble substances. The oxygen passing through the membrane is reduced on the electrode, generating a weak diffusion current, which is proportional to the dissolved oxygen content in the water sample at a certain temperature.
