Hanna HI4430B Gel Filled ORP Electrode with Gold Contact

Hanna HI4430B Gel Filled ORP Electrode with Gold Contact

The Hanna HI4430B Gel Filled ORP Electrode with Gold Contact is a durable ORP electrode designed for general-purpose oxidation-reduction measurements across a broad range of applications. It features a gold (Au) sensing pin, gel electrolyte, and a PEI (PolyEther-Imide) body, offering both chemical resistance and low-maintenance operation. Additionally, it connects via a standard BNC connector for easy integration with a wide range of instruments.

Key Features

• Gold Pin for Specialized Redox Environments: The gold sensing tip is particularly suited for applications involving proteins, sulfides, or biological media, where platinum sensors are prone to fouling.

• Gel-Filled for Low Maintenance: Because the electrode is gel-filled, it requires no refilling, making it ideal for continuous or routine measurements.

• PEI Body for High Durability: The PolyEther-Imide (PEI) housing provides excellent chemical resistance and mechanical strength, enabling reliable use in tough conditions.

• BNC Connector for Broad Compatibility: With its coaxial BNC connector, the electrode easily pairs with most pH/ORP meters in laboratory and field settings.
