The Go Direct Voltage Probe combines a wide input voltage range and high precision, making it an excellent choice for investigations of both AC/DC circuits and electromagnetism. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.

Description

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 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.

The Go Direct Voltage Probe can be used 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 Go Direct robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from our free Graphical Analysis 4 app. 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.

Wired or Wireless—The Flexibility to Choose

Our Go Direct sensors connect directly to your mobile device, Chromebook, or computer using our free Graphical Analysis 4 app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth, allowing you to choose the solution best for your classroom or laboratory.
