Differential Voltage Sensor

The Differential Voltage Probe is the preferred voltage sensor in cases where more than one voltage sensor will be used in the same circuit.
Explore the basic principles of electricity and measure voltages in low voltage AC and DC circuits. 
Use multiple Differential Voltage Probes to explore series and parallel circuits.
The Differential Voltage Probe reports the potential difference between the red and black leads. 
With a range of ±6.0 V, this system is ideal for use in battery & bulb circuits.
