Q1: What is a dissolved oxygen meter?
A1: A dissolved oxygen meter is a device used to measure the amount of oxygen dissolved in a liquid, typically water. Dissolved oxygen (DO) is a crucial parameter for assessing water quality because it directly impacts the health and viability of aquatic life.
Q2: What does a dissolved oxygen meter measure?
A2: A dissolved oxygen meter measures the concentration of oxygen dissolved in water, typically in milligrams per liter (mg/L) or parts per million (ppm). This measurement is crucial for assessing water quality, ensuring the health of aquatic life, and optimizing processes in wastewater treatment and various industrial applications.
Q3: Is a dissolved oxygen meter accurate?
A3: Yes, a dissolved oxygen meter is generally accurate, especially when properly calibrated and maintained. Modern meters, whether using electrochemical or optical sensors, provide precise measurements of dissolved oxygen levels in water. Regular calibration against known standards and proper maintenance of the sensor are essential to ensure continued accuracy.
Tips: What is the fluorescence method of measuring dissolved oxygen?
This method uses the quenching phenomenon of oxygen to calculate the level of DO. Fluorescence from a fluorescent material excited by light from a blue light-emitting diode (LED) is quenched by oxygen passed through a DO permeable layer. When the dye is excited by a specific wavelength of light, it emits fluorescence. The presence of oxygen quenches this fluorescence, meaning the more oxygen present, the less fluorescence is emitted. The sensor measures the intensity and lifetime of the fluorescence, which are inversely proportional to the dissolved oxygen concentration. This method is known for its high accuracy, stability, and low maintenance requirements.
