Definition of Optical Dissolved Oxygen Meter
Definition of Optical Dissolved Oxygen Meter
An Optical Dissolved Oxygen Meter is a device designed to measure the amount of oxygen dissolved in water or other liquids. It operates using optical sensors that detect changes in light absorption or fluorescence caused by oxygen molecules. These sensors typically consist of a light source, a photodetector, and a special sensing element coated with a luminescent dye. When oxygen interacts with the dye, it affects the light emitted or absorbed, allowing the device to calculate oxygen levels accurately. This technology is favored for its high sensitivity, quick response time, and minimal maintenance needs. It is suitable for continuous monitoring in environments like lakes, rivers, industrial effluents, and aquaculture systems. The device's ability to provide real-time data helps in making immediate decisions, ensuring water safety and compliance with environmental regulations.
How It Works
How It Works
Sensor Activation: The device's optical sensor is powered on, emitting a specific wavelength of light into the water sample.
Light Interaction: The emitted light interacts with a luminescent dye embedded in the sensor. The dye fluoresces when excited by the light source.
Oxygen Detection: Oxygen molecules in the water quench the fluorescence or alter the light absorption properties of the dye, affecting the intensity of the emitted light.
Signal Conversion: The photodetector measures the changes in light intensity or wavelength, converting these signals into electrical data.
Data Processing: The device's internal processor calculates the dissolved oxygen concentration based on the optical signals, providing a digital readout.
Data Transmission: The measurement data can be transmitted wirelessly or via cable to monitoring systems for analysis and record-keeping.
