Vernier's 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.

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. Vernier 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 Vernier Go Direct™ robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from Vernier's free Graphical Analysis™ 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
Vernier's Go Direct™ sensors connect directly to your mobile device, Chromebook or computer using Vernier's free Graphical Analysis™ 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.

GAPRO Vernier Graphical Analysis™ Pro includes all the features of the free Vernier Graphical Analysis app, plus enhanced functions for more advanced analysis. Its illustrative experiment videos and interactive graphing capabilities inspire students to explore crucial scientific concepts and analyze data in new complex and insightful ways.
GAPRO is compatible with most Vernier sensors and multiple operating systems and devices.

Vernier and Kidwind products are designed for educational use. They are not appropriate for industrial, medical or commercial applications. Details

  • Warranty: 5 years (1 year on battery) This product is used in teaching these Australian Curriculum codes:
    ACSSU190 - Physical Sciences - Energy Conservation - Energy conservation in a system can be explained by describing energy transfers and transformations
    ACSPH044 - Thermal nuclear and electrical physics - Electrical circuits - Circuit analysis and design involve calculation of the potential difference across, the current in, and the power supplied to, components in series, parallel and series/parallel circuits
    ACSPH039 - Thermal nuclear and electrical physics - Electrical circuits - Energy is conserved in the energy transfers and transformations that occur in an electrical circuit
    ACSPH041 - Thermal nuclear and electrical physics - Electrical circuits - Energy is required to separate positive and negative charge carriers; charge separation produces an electrical potential difference that can be used to drive current in circuits
    ACSPH042 - Thermal nuclear and electrical physics - Electrical circuits - Power is the rate at which energy is transformed by a circuit component; power enables quantitative analysis of energy transformations in the circuit
    ACSPH043 - Thermal nuclear and electrical physics - Electrical circuits - Resistance for ohmic and non­ohmic components is defined as the ratio of potential difference across the component to the current in the component
    ACSPH040 - Thermal nuclear and electrical physics - Electrical circuits - The energy available to charges moving in an electrical circuit is measured using electric potential difference, which is defined as the change in potential energy per unit charge between two defined points in the circuit
    ACSCH103 - Equilibrium acids and redox reactions - Oxidation and reduction - A range of reactions, including displacement reactions of metals, combustion, corrosion, and electrochemical processes, can be modelled as redox reactions involving oxidation of one substance and reduction of another substance
    ACSCH104 - Equilibrium acids and redox reactions - Oxidation and reduction - Oxidation can be modelled as the loss of electrons from a chemical species, and reduction can be modelled as the gain of electrons by a chemical species; these processes can be represented using half­ equations
    ACSCH106 - Equilibrium acids and redox reactions - Oxidation and reduction - The relative strength of oxidising and reducing agents can be determined by comparing standard electrode potentials
    ACSPH110 - Gravity and electromagnetism - Electromagnetism - A changing magnetic flux induces a potential difference; this process of electromagnetic induction is used in step­up and step­down transformers, DC and AC generators, and AC induction motors
    ACSPH111 - Gravity and electromagnetism - Electromagnetism - Conservation of energy, expressed as Lenz’s Law of electromagnetic induction, is used to determine the direction of induced current
    ACSSU155 - Physical Sciences - Energy Forms - Energy appears in different forms, including movement (kinetic energy), heat and potential energy, and energy transformations and transfers cause change within systems
