The Dissolved Oxygen Probe is great for biology, chemistry, ecology, or integrated science courses. It can be\\ used to perform a wide variety of experiments to determine changes in dissolved oxygen levels, one of the\\ primary indicators of the quality of an aquatic environment.\\

Built-in temperature compensation lets you calibrate in the lab, then make measurements outdoors without having\\ to recalibrate.Disposable caps with pre-fit membranes allow you to quickly and conveniently change membranes.\\
Calibrate in the units you choose: % dissolved oxygen, mg/L, or ppm dissolved oxygen\\
