ISE concentration meters measure specific ionic concentrations within aqueous solutions using ion-selective electrodes. These benchtop meters are utilized in chemical analysis and research and the membranes may be made of crystalline, glass, enzymes, and ion-exchange resins. The Thermo Scientific™ Orion™ Dual Star™ pH and ISE Benchtop Meter, ideal for high throughput lab analysis, records reliable pH, ion concentration, mV, ORP, and temperature measurements efficiently.
