Best Dissolved Oxygen Sensor Probe Meters

Optical Dissolved Oxygen still uses a probe to measure the dissolved oxygen, but instead of monitoring a reaction, the probe and meter monitor luminescence. Simply, there is a blue light emitted by the probe, and the blue light excites the light sensitive material in the probe cap. As the material calms back down, it releases a red light, and it is measured when it hits a light sensor. If dissolved oxygen is present, it will suppress the red light. The intensity, lifespan of the light (decay), and frequency of the red light are all dependent on the concentration of oxygen. Optical dissolved oxygen probes are also able to provide a continuous measurement of your sample. Optical DO probes are a bit more affected by humidity than other probes.


DO-700 Dissolved Oxygen analyzer adopts fluorescence method to measure dissolved oxygen. 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.
