The Go Direct® Voltage Probe combines a wide input voltage range and high precision, making it an excellent choice for lab investigations of both AC/DC circuits and electromagnetism. Use this differential probe to measure the voltage in simple circuits, to study basic principles of electrochemical cells, or to investigate the resistivity of different metals. Comes with micro USB cable.

Tariffs have driven up the cost of this item significantly. We apologize for the price increase. We are absorbing some of the impact to help teachers but are forced to pass most of it along.

Product Details
The Go Direct® Voltage Probe combines a wide input voltage range and high precision, making it an excellent choice for lab investigations of both AC/DC circuits and electromagnetism. Use this differential probe to measure the voltage in simple circuits, to study basic principles of electrochemical cells, or to investigate the resistivity of different metals.

With a range of ±15 V, this system is ideal for use in "battery and bulb" circuits. Go Direct® Voltage Probe is capable of kHz sampling and mV resolution, so you can also use it to capture more difficult electric potentials, such as the electromagnetic field induced in a coil by a moving magnet. This single sensor can take the place of several voltmeters in your classroom.

Use the Go Direct® Voltage Probe in a variety of experiments:

• Measure potential difference at various places in series and parallel circuits
• Investigate Ohm's law in simple circuits
• Measure the voltage across a capacitor in RC and RLC circuits
• Explore Faraday's law and induced EMFs in a coil of wire

Rechargeable Battery—Ready When You Are
The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from the award-winning Vernier Graphical Analysis® app, as well as LabQuest® 3. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wireless or Wired—The Flexibility to Choose
The Go Direct® sensor connects directly to your mobile device and Chromebook™ or other computer using the Vernier Graphical Analysis® app—no additional equipment or software purchases are necessary. The sensor also can be used wired via USB or wirelessly via Bluetooth® technology, allowing you to choose the solution best for your classroom or laboratory.
