Flow-Through Electrode Holder

The Flow-Through Electrode Holder integrates standard rod-type pH, ORP, reference, or conductivity electrodes directly into a flowing electrolyte stream, in either continuous flow-through or dead-end Luggin-capillary mode. Built in chemically resistant polypropylene with EPDM and Viton O-ring sealing, it accepts electrodes from 3 mm up to 17 mm in diameter across four holder variants, and is designed to pair directly with Redox Flow’s X-Cell's reference-electrode ports. A complete kit of tubing, a syringe for galvanic connection, and hose clamps ships with every holder.

• Two Measurement Modes: Flow-through for continuous monitoring or dead-end Luggin-capillary mode for isolated reference measurement.
• Broad Electrode Compatibility: Four diameter variants (3–7, 7–10, 10–13, 13–17 mm OD) fit standard pH, ORP, reference, and conductivity electrodes.
• Dual O-Ring Sealing: EPDM and Viton O-rings both included for broad chemical compatibility.
• X-Cell Integration: Designed to pair directly with the X-Cell's dedicated reference-electrode ports.
• Complete Connection Kit: Includes PTFE tubing, a syringe for galvanic connection, hose clamps, and support rings.
• Elevated Temperature Rated: Operates up to 90 °C without damaging the reference electrode.
