Vernier - Water Quality - TDS (Total Dissolved Solids)

In this activity, students will use the Vernier Conductivity Probe to measure the Total Dissolved Solids in samples of water.

In this activity, students measure the Total Dissolved Solids in samples of local water using the Conductivity Probe. The Single Point mode averages the readings over 10 seconds.
Students can also use the Conductivity sensor with the Events with Entry if they need to sample multiple sites.
