Na⁺ · Smart Sodium IonSensor

M200 Smart Sodium IonSensor

The glass-membrane ion-selective electrode (ISE) measures sodium ion from 0.1 to 23,000 ppm with 0.001 ppm resolution, +/-5%FS accuracy, and automatic temperature compensation. IP68 protection, submersion or flow-through installation, and RS485 output support reliable monitoring in process water and water-treatment systems.
