Go Direct Electrode Amplifier

Item code
GDX-EA

 

The Vernier Go Direct sensors offering direct, wireless (Bluetooth) or wired (USB) connectivity to devices (computers, tablets, phones) without needing a separate interface. It uses Vernier's free Graphical Analysis software for data collection and analysis, providing greater versatility, portability and modern compatibility with various platforms.

The Go Direct Electrode Amplifier is a mV and pH amplifier that connects to Vernier electrodes and compatible third-party BNC electrodes. It connects via Bluetooth® wireless technology or via USB to your device.

$191.00 $210.10

The 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.

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