Use our Electrode Amplifier to collect data with almost any electrode that has a BNC connector. This includes electrodes from Vernier such as one of our pH, ISE, or ORP electrodes, or third-party electrodes, such as pH, ISE (ion-selective electrode), or ORP (oxidation-reduction
potential). The Electrode Amplifier can produce an output in mV, pH (when using a pH electrode). You can also perform your own 2-point linear calibration.
Note: Vernier products are designed for educational use. Our products are not designed nor are they recommended for any industrial, medical, or commercial process such as life support, patient diagnosis, control of a manufacturing process, or industrial testing of any kind.
Choose a platform below to see its compatibility requirements.
CBL 2 and LabPro interfaces cannot be used with TI-84 Plus CE calculators.
DataMate cannot be used with color screen TI-84 Plus calculators; use EasyData with these calculators.
Connect the sensor to the interface (LabQuest Mini, LabQuest 2, etc.).
Start the appropriate data-collection software (Logger Pro, Logger Lite, LabQuest App, or Graphical Analysis 4) if not already running, and choose New from File menu. The software will identify the sensor and load a default data-collection setup. You are now ready to collect data.
If you are collecting data using a Chromebook™, mobile device such as iPad® or Android™ tablet, or a Vernier wireless interface, please see the following link for up-to-date connection information:
Do not wrap the cable tightly around the sensor for storage. Repeatedly doing so can irreparably damage the wires and is not covered under warranty.
How the Sensor Works
The Electrode Amplifier is a circuit that allows the millivolt output of an electrode to be monitored by an interface. The electrode is connected to the BNC connector on one end of the amplifier. The cable from the Electrode Amplifier connects to the interface.
The Electrode Amplifier will report values in units of pH. If an ORP or ISE electrode is attached, however, you can choose to read in units of mV. Custom linear 2-point calibrations can also be performed if desired.
