LH-DO59 Digital Dissolved Oxygen Sensor

OVERVIEW

This sensor is based on polarography to measure dissolved oxygen in water. The dissolved oxygen sensor is composed of cathode and anode. The cathode is platinum electrode and the anode is silver / silver chloride electrode. The cathode and anode are immersed in the electrolyte chamber, which is isolated from the external measurement environment through a diaphragm. Dissolved oxygen diffuses to the cathode through the diaphragm and is reduced on the cathode to generate current. The reduction current is positive with the transfer rate of dissolved oxygen into the electrolyte. At a given temperature, the current is proportional to the partial pressure of oxygen in the water.

FEATURES & BENEFITS

• Adopt the principle of polarography, the test water sample needs to maintain fluidity.

• With appropriate oxygen permeable membrane, reference electrode and electrolyte, the electrode has better measurement accuracy and stability.

• Built in temperature sensor with automatic water temperature compensation function.

• Supports MODBUS / RS485 output.

APPLICATION

It can be used for the determination of dissolved oxygen in aquaculture river monitoring, sewage treatment, swimming pool and other water.
