Hanna HI4430B/3 Gel Filled ORP Electrode with Gold Contact
The Hanna HI4430B/3 Gel Filled ORP Electrode with Gold Contact is a reliable and low-maintenance oxidation-reduction potential (ORP) electrode, ideal for general-purpose applications across environmental, laboratory, and industrial settings. Featuring a gold pin sensing element, a PEI body, and a gel electrolyte, this electrode delivers consistent performance even in chemically challenging environments.
Key Features
Gold Pin for Enhanced Stability in Complex Samples: The electrode’s gold tip provides superior resistance to fouling from proteins or sulfides—making it an excellent choice where platinum sensors may be unsuitable.
Gel Electrolyte for Maintenance-Free Operation: Since the internal solution is gel-filled, users can avoid frequent refilling and enjoy hassle-free usage during extended monitoring tasks.
Durable PEI Body: Built from PolyEther-Imide (PEI), the body offers robust chemical resistance and mechanical strength, ensuring reliability in both field and laboratory environments.
BNC Connector for Broad Compatibility: The standard BNC connector allows easy and secure connection to most ORP meters without the need for adapters.
