VERNIER GO DIRECT ELECTRODE AMPLIFIER
Vernier's Go Direct Electrode Amplifier is an mV and pH amplifier that connects to Vernier electrodes and compatible third-party BNC electrodes. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.

The Vernier Go Direct Electrode Amplifier offers an affordable way to expand your experiment options. Its BNC connector provides the flexibility to attach and remove a Vernier electrode such as the pH electrode, flat pH electrode, ORP electrode, ISE electrode or a third-party electrode. You can explore pH one day and potassium concentrations the next.

Please note that measurements other than pH are measured in mV and you will need to calculate mg/L from this mV reading.
GDX-ISEA Vernier Go Direct Ion-Selective Electrode Amplifier measures directly in mg/L

Because the Vernier Go Direct Electrode Amplifier is compatible with third-party electrodes, students learn consistent calibration and handling techniques on one amplifier using one software program. When electrodes expire or become damaged you need only replace the electrode, lowering your overall equipment costs.

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. Vernier 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.
