School Savers - Vernier GDX-PH Go Direct pH Sensor

Vernier GDX-PH Go Direct pH Sensor

The Go Direct pH Sensor is an important and versatile sensor for lab and field activities alike. It gives students the freedom to explore pH without the inconvenience of wires‚ no more spilled solutions or dangling wires. The Go Direct pH transmits live readings and captures data in real-time.

Use this sensor in a variety of experiments:
Conduct acid-base titrations.
Monitor pH change during chemical reactions.
Test the pH and alkalinity of bodies of water.
Investigate household acids and bases.

This sensor is comprised of a pH electrode connected to a Go Direct Electrode Amplifier via a BNC connector. This design enables you to use the Go Direct Electrode Amplifier with other Vernier electrodes, such as the Flat pH Electrode, ORP Electrode, ISE electrode, or a third-party electrode.

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™ Pro 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™ Pro 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 solution best for your classroom or laboratory.
