Water quality monitoring is of paramount importance in various industries, including sewage treatment plants, water purification facilities, aquaculture, and industrial processes. The accurate measurement of dissolved oxygen (DO) is a critical aspect of this monitoring, as it serves as a key indicator of water quality. Traditional DO sensors have limitations, but with the advent of optical DO probes like the DOG-209FYD by Shanghai BOQU Instrument Co., Ltd., a new era of real-time data logging and reliable monitoring has dawned.
Optical DO Probes Revolutionize Water Quality Monitoring
Optical DO probes, also known as optical dissolved oxygen sensors, have revolutionized the way we monitor water quality. Unlike traditional electrochemical sensors, optical DO probes use fluorescence measurement to determine the concentration of dissolved oxygen. The principle behind this method is fascinating: blue light excites a phosphor layer, causing it to emit red light. The time it takes for the fluorescent substance to return to its ground state is inversely proportional to the concentration of oxygen. This unique approach provides several advantages over conventional sensors.
One of the primary advantages of optical DO probes is that they do not consume oxygen during the measurement process. This is a significant breakthrough, as it ensures that the measurement remains stable and reliable over time. Unlike electrochemical sensors, which can deplete the oxygen in the sample, optical DO probes maintain the integrity of the water being monitored.
Optical DO Probe Calibration: Tips and Tricks
Calibrating a DO probe is a crucial step in ensuring accurate measurements. The DOG-209FYD optical DO probe makes calibration a breeze with its user-friendly features. Calibration can be done in two ways: air automatic calibration and sample calibration. Air automatic calibration is a quick and straightforward method that uses the natural presence of oxygen in the air. Sample calibration, on the other hand, involves calibrating the probe with a known sample of water with a known DO concentration. Both methods are supported by the DOG-209FYD, providing flexibility for different applications.
The sensor’s calibration process is complemented by a maintenance prompt feature, allowing users to set customized prompts that are automatically triggered when maintenance is required. This proactive approach ensures that the probe remains in optimal working condition, minimizing downtime and enhancing data accuracy.
