1. Product Introduce

The sensor is a Galvanic cell type dissolved oxygen water detection sensor. Oxygen molecules in the solution to be tested pass through the

selective membrane of the sensor, and corresponding reductionor oxidation reactions occur on the cathode and anode inside the sensor. At

the same time, a current signal is generated. The current is proportional to the dissolved oxygen concentration.The magnitude of the

dissolved oxygen is determined by the magnitude of the current.

2. Product Features

Ø Low power consumption

Ø High accuracy

Ø Linear output

Ø No need to change the breathable membrane

Ø No need to change the electrolyte

Ø No need the external power

3. Main application

Widely used in laboratory scientificresearch, aquaculture, environmental protection, etc.
