Description
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
