Yes, it is possible to use a Vernier Ion-Selective Electrode (ISE) with an Arduino microcontroller. However, we do not recommend this combination unless you are familiar with the sensor’s user manual and the complexity of how the sensor works, have become familiar with the Nernst Equation, and have an understanding of the continuous need for calibration.
Note: Vernier ISEs are not designed for long-term, continuous use (in no circumstances should the sensor be submerged in a solution for greater than 24 hours). They are designed for educational lab applications where sensors are calibrated, and tests are conducted and completed in a short time period. ISE sensor membranes have a limited shelf-life and change over time, so regular calibration (perhaps every use) must be performed. Vernier ISEs are for educational use only, not for industry, medical, hobby, or commercial use.
Go Direct ISE with Arduino
Go Direct ISE readings are reported in mV by default. If you choose to change the sensor channel to read concentration, you will want to calibrate the sensor in the Vernier Graphical Analysis app. If you wish to convert the mV reading to concentration manually, refer to the How the Sensor Works section of the sensor’s user manual.
