Techne Ion Selective Electrodes

Ion Selective Electrodes

An Ion-selective electrode (ISE) has a sensor that converts the activity of a specific ion dissolved in a solution into an electrical potential/signal which can be measured by a pH meter. The sensing part of the electrode is made as an ion-specific membrane, along with a reference electrode. Types of ISEs Click for more information

Ion Selective Electrodes (ISEs)
There are three types of ISEs: Half-cell, Combination and Flow Plus - all of which have advantages in certain applications. It is important to select the correct ISE for your application. Be sure to purchase the right type of connector lead with your ISE for your Meter
