30-Volt Voltage Probe

30-Volt Voltage Probe product image

This sensor is used to measure voltages in the range of -30 to +30 volts.


This sensor is used to measure voltages in the range of -30 to +30 volts. Use this sensor in experiments that involve voltages larger than 10 volts, such as when working with large solar panels. Since this voltage probe covers such a wide voltage range, its resolution is lower than our Differential Voltage Probe, which we recommend for most experiments.

The removable leads on the 30-Volt Voltage Probe are heavy duty and have shrouded banana plugs to meet European safety standards.
