Principle - Optical Dissolved Oxygen Meter

Unlike conventional dissolved oxygen analyzer meter, the A.YITE GE-135 Luminescent optical dissolved oxygen analyzer meter's sensing element utilizes fluorescence to measure dissolved oxygen. The sensing element in the optical dissolved oxygen transmitter consists of a fluorescing compound suspended stably in a robust optical "window". A light source at controlled wavelength briefly pulses the optical window. This "excites" the fluorescent material, causing it to emit a specific wavelength of light. The intensity of this fluorescence or light is determined by the amount of dissolved oxygen in the water in contact with the optical window. A highly stable and accurate optical sensor circuit inside the A.YITE GE-135 Luminescent optical dissolved oxygen analyzer meter measures the emitted fluorescence. As a result, the A.YITE GE-135 Luminescent optical dissolved oxygen analyzer meter provides accurate dissolved oxygen measurements over long periods of time without the need for re-calibration.

Advantages than Traditional Dissolved Oxygen Sensors

Traditional Galvanic and Polargraphic dissolved oxygen sensors have been used to measure dissolved oxygen in water. Galvanic and polargraphic dissolved oxygen sensors utilize chemical electrical signatures based on a semi-permeable membrane covering electrodes that are immersed in an electrolyte. These dissolved oxygen sensors have been poorly suited to long term reliable and accurate monitoring of lakes, streams, and rivers. The semi-permeable membranes and electrolyte require frequent replacement. The Galvanic and Polargraphic dissolved oxygen sensor electrodes are subject to deterioration and "poisoning". These dissolved oxygen sensors require constant water flow otherwise oxygen consumption occurs causing inaccurate at readings. Galvanic and Polargraphic dissolved oxygen sensors require frequent calibration resulting in high upkeep and labor costs.

Unlike conventional Galvanic and Polargraphic dissolved oxygen sensors, the A.YITE GE-135 Luminescent optical dissolved oxygen analyzer meter have no consumable components that require replacement, minimizing servicing requirments. Neither do the A.YITE GE-135 Luminescent optical dissolved oxygen analyzer meter consume oxygen. Consequently the measurement of dissolved oxygen by the optical dissolved oxygen sensor is unaffected by water flow. The A.YITE GE-135 Luminescent optical dissolved oxygen analyzer meter can even be deployed in stagnate groundwater bores. Because of the copper anti-biofoul ring and the general construction of the A.YITE GE-135 Luminescent optical dissolved oxygen transmitters, they are unaffected by pollutants and poisons and highly resilient to bio fouling. The A.YITE GE-135 Luminescent optical dissolved oxygen analyzer meter have extremely stable electronics - a calibration interval of 1 year is typical.

The A.YITE GE-135 Luminescent optical dissolved oxygen analyzer meter can be used to monitor dissolved oxygen in almost any liquid, including wines, beer, and milk. The A.YITE GE-135 Luminescent optical dissolved oxygen sensors are not affected by color of the liquid. Bubbles or aeration do not affect the A.YITE GE-135 Luminescent optical dissolved oxygen analyzer meter's measurements. The A.YITE GE-135 Luminescent optical dissolved oxygen sensors can also be mounted in process lines for quality assurance.
