Voltage & Current Sensor 20V 1A

Bluetooth | USB | Huge Battery Life | Independent Logging

This sensor is both a Voltage and Current sensor combined in one package. It can be used to measure both electric current and the potential difference across a component in low voltage AC or DC circuits.

The Voltage sensor measures the difference in potential between two points in a circuit in a range between -20 V to +20 V. The Current sensor measures the current flowing in a circuit in a range of -1 A to +1 A (±1000 mA).

Use with 4 mm plug leads (not supplied) to connect to most standard available electronics kits and school based power supplies.
