MW-O201 sensor is polarographic type dissolved oxygen water quality detection sensor. At a certain polarization potential, the dissolved oxygen in the water will pass through the oxygen permeable membrane and REDOX reaction will occur on the surface of the working electrode. The resulting current is proportional to the concentration of dissolved oxygen in the water, and the concentration of dissolved oxygen in the water is calculated by measuring the size of the current.

Application

It is widely used in the detection of dissolved oxygen water quality in laboratory research, aquaculture, environmental protection and other fields.

Features

Quick response, good stability, high precision, long life and easy maintenance.
