The Wireless Voltage sensor W60 is designed for exploring the basic principles of electricity. With a wide input voltage range of – 15 to +15 V this sensor can be used to measure voltages in AC and DC circuits. The sensor is equipped with two 4-mm wires with banana plugs and alligator clips. The sensor has differential inputs, which means that measurements can be done directly across circuit elements without the constraints of common grounding. It can be used to measure positive potentials, as well as negative potentials.

The sensor can be used wirelessly via Bluetooth or wired via USB. The sensor is equipped with an OLED color display which shows some sensor information and the measured by the sensor values. This makes the sensor suitable to use as an independent measuring instrument.

The sensor can be used wirelessly via Bluetooth or wired via USB with the Coach or Coach Lite programs/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).
