SUP-DO700 Optical dissolved oxygen meter

SUP-DO700 dissolved Oxygen meter 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.

  • Introduction

SUP-DO700 Dissolved oxygen meter measures the dissolved oxygen by the fluorescence method, and the emitted blue light is irradiated on the phosphor layer. The fluorescent substance is stimulated to emit red light, and the oxygen concentration is inversely proportional to the time when the fluorescent substance returns to the ground state. By using this method to measure the dissolved oxygen, it will not produce oxygen consumption, thus assuring data stability, reliable performance, no interference, and simple installation and calibration.
