Understanding Dissolved Oxygen Meters
A laboratory dissolved oxygen meter is an essential instrument used to measure the concentration of dissolved oxygen (DO) in liquid samples. It is widely used in water quality testing, environmental monitoring, and biochemistry research. By determining the DO levels in water, researchers can assess the health of aquatic ecosystems or the efficiency of biological processes, such as fermentation or respiration in microbial cultures. These meters operate by using either electrochemical sensors or optical sensors, providing highly accurate and reliable results. Regular calibration ensures precision, making the dissolved oxygen meter indispensable for scientific experiments and industrial applications that require exact oxygen monitoring.
