LH-DO59 Digital 12vdc Dissolved Oxygen Sensor Measuring Range 0~20mg/L 0~ 200.0%

LH-DO59 Digital Dissolved Oxygen Sensor

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.
