The Orion 9746BNWP ionplus® Nitrite Electrode offers additional benefits from its Sure-Flow® combination reference design. With this electrode, a separate reference electrode is unnecessary, making it convenient to use with small sample volumes. The free-flowing Sure-Flow junction assures stable, drift-free potentials. When measuring dirty samples that would clog conventional electrode junctions, the Sure-Flow junction can be cleaned by pressing the electrode cap.

Teamed with the introduction of the Orion Star Series, Thermo Scientific has also introduced the new WP- waterproof and secure electrode connectors, a revolutionary feature of the new Orion Star Series Meters. The BNWP connector provides a waterproof and secure connection when used with the new Orion Star Series meters. The BNWP connector is compatible with any standard BNC connector both on Orion meters and competitive meter models.

U.S. Standard, waterproof BNC and BNC electrodes have 1 m cables.
