Online Dissolved Oxygen Meter

Online Dissolved Oxygen Meter T-DO1100 adopts the fluorescence method to measure dissolved oxygen. The cap of the sensor is coated with 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.
