Vernier VP-BTA Voltage Probe

The Voltage Probe is a bipolar sensor. The black lead is grounded along with the interface, and the sensor reports the potential difference between the red lead and ground. It can be used to measure the potential in DC or AC circuits. You might also consider the Differential Voltage Probe. Multiple Differential Voltage Probes can be connected to a circuit without the use of a common grounding terminal.
