Replacement ORP Redox Electrode, Oxidation‑Reduction Probe with 300cm Cable & BNC Connector, Compatible With Most ORP Meters

This high‑performance replacement ORP (Oxidation‑Reduction Potential) electrode is a perfect spare‑part probe for your water‑quality testing equipment. Designed to measure the oxidation‑reduction value of water solutions accurately, it works as an ideal substitute for worn‑out, aging or damaged ORP sensors.

Fitted with a long 300‑centimeter flexible cable and industry‑standard BNC connector, this ORP redox probe supports quick, tool‑free plug‑and‑play installation. The extra‑long wire gives you great flexibility for deep‑water sampling, tank monitoring, lab testing, aquariums, hydroponic systems, swimming‑pool water detection and industrial water‑quality projects. No complicated wiring or adapter is required for most devices equipped with a BNC port.

Built‑with premium sensing glass tip, the electrode delivers fast, stable and repeatable ORP readings. It comes with a protective sensor storage cap. You can fill the cap with preservation solution when the probe is not in use, effectively protecting the sensitive sensor tip, extending the service life of this electrode and preventing contamination or dry‑out damage.

This ORP replacement probe enjoys broad compatibility. It fits most mainstream ORP testers, ORP controllers and potentiometers with BNC‑interface on the market. Suitable for both laboratory liquid analysis and on‑site water‑quality monitoring. Widely used for hydroponics, aquaculture, spa & swimming pool, waste‑water treatment, drinking‑water testing and other water‑related measurement scenarios.
