Go Direct® Ion-Selective Electrode Amplifier
The Go Direct Ion-Selective Electrode Amplifier is a mV and mg/L amplifier that connects to Vernier Ion-Selective Electrodes and compatible third-party BNC ion-selective electrodes. It connects via Bluetooth® wireless technology or via USB to your device.
Expand your water quality, environmental, and agriculture experiment options with the wireless Go Direct Ion-Selective Electrode Amplifier. The versatile BNC connector allows students to easily remove and attach various ion-selective electrodes, such as the Go Direct Nitrate Ion-Selective Electrode, Go Direct Ammonium Ion-Selective Electrode, Go Direct Calcium Ion-Selective Electrode, Go Direct Chloride Ion-Selective Electrode, or Go Direct Potassium Ion-Selective Electrode.
Because the Go Direct Ion-Selective Electrode Amplifier is compatible with third-party electrodes, students learn consistent calibration and handling techniques on one amplifier using one software program. When an electrode expires or becomes damaged, you need only replace the electrode and not the entire sensor—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 our free Graphical Analysis™ 4 app or LabQuest 3 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.
Important: Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results; they are not recommended for middle school or elementary students.
