The directION Sodium combination ISE has a solid state PVC polymer membrane with an integral liquid reference system. The electrode is designed for the detection and analysis of Sodium ions in aqueous solutions and is suitable for use in the laboratory and as a component in on-line analysers.

The Flow plus range incorporates two solid state ISE’s in one 12 mm Epoxy body. One acts as the Sensor whilst the other is incorporated into the reference system. Your Flow plus combination ISE therefore does not require a separate reference electrode, making it convenient to use with small sample volumes. The reference half cell has a free-flowing liquid junction which will reduce drift and provide more stable readings than conventional ISE’s. Flow plus electrodes are ideal for measuring awkward or dirty samples, which would clog conventional reference electrodes.
