Orion Sure-Flow Combination Electrodes

Thermo Scientific Orion Sure-Flow Combination Electrodes quickly and efficiently measures free ions in aqueous solutions. Since it contains both a sensing electrode and a reference element, it can be used with smaller sample volumes.

A free-flowing Sure-Flow® junction ensures stable, drift-free potentials – if the junction clogs, just flush it clean by pressing the cap. The electrode has a solid-state sensing membrane and epoxy body with a waterproof BNC connector.
