Students use the Dissolved Oxygen Probe to measure the concentration of dissolved oxygen in water from streams and rivers. They correlate the availability of dissolved oxygen to temperature, pressure, and salinity.
Sampling from local water sources, students measure the dissolved oxygen levels. The Single Point method averages readings for 10 seconds.
If students are sampling from several locations, Events with Entry can be used to collect the data.
