Sensorex offers a range of low-cost Ion Selective Electrodes. These convenient combination electrodes use just one electrode to measure ppm of ions. All Sensorex ISEs are housed in rugged plastic bodies and offer a choice of fixed cable or detachable cable design. Use these electrodes with your ISE meter, pH meter in mV mode, or with any mV input device. Sensorex ISEs require little to no cleaning and are virtually maintenance free (no reference or ISE refill solution required).
