MIK-DO7012 Optical dissolved oxygen sensor

MIK-DO7012 Optical type dissolved oxygen sensor, an intelligent online chemical analyzer. The cap of the sensor is coated with a luminescent material. Blue light from an LED illuminates the luminescent chemical. The luminescent chemical instantly becomes excited and releases red light. The time and intensity of red light are inversely proportional to the concentration of oxygen molecules, So the concentration of oxygen molecules is calculated.
