Go Direct Glass-Body pH Electrode with BNC Connector

The Go Direct Electrode Amplifier (SE157392) is a mV and pH amplifier that 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 (SE157560), Flat pH Electrode (SE157688), Glass pH Electrode (SE157696), or a third-party electrode. Note - electrodes cannot be used without amplifier.

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. 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® wireless technology, allowing you to choose the solution best for your classroom or laboratory.

• The Go Direct pH BNC Electrode is a gel-filled combination pH electrode designed to make measurements in the pH range of 0 to 14. A polycarbonate body that extends below the glass sensing bulb of the electrode makes this probe ideal for the demands of a middle school, high school, or university level science class or for making measurements in the environment. The gel-filled reference half cell is sealed—it never needs to be refilled.
• Go Direct Flat pH BNC Electrode can be used for any lab or demonstration that can be done with a traditional pH meter, including acid-base titrations, monitoring pH in an aquarium, and investigating the water quality of streams and lakes.
• The Go Direct Glass-Body pH BNC Electrode can be used in non-aqueous solutions and solutions that contain organic solvents, strong acids, or strong bases. The electrode features a sealed, gel-filled Ag-AgCl combination reference electrode and uses a BNC connector.
