Hanna HI4211T ORP Au pin plastic (PEI) body screw cap S7
The Hanna HI4211T ORP Au pin plastic (PEI) body screw cap S7 is a robust ORP electrode designed for long-lasting performance in both laboratory and industrial environments. Featuring a gold (Au) pin, gel-filled reference system, and a plastic (PEI) body, this electrode is well-suited for applications where chemical resistance and easy installation are essential. It connects via an S7 screw head and is compatible with PG13.5 threaded ports, allowing for flexible integration.
Key Features
Gold Pin for High-Performance Redox Measurement: The Au sensing element offers excellent stability and response in oxidation-reduction environments, especially in samples containing proteins or sulfides, where platinum sensors may suffer from fouling.
Cloth Junction with Gel Electrolyte: The renewable cloth junction ensures prolonged electrode life and minimizes clogging, while the gel-filled design eliminates the need for frequent maintenance.
Durable Plastic (PEI) Body: Built with PolyEther-Imide, the electrode body provides outstanding chemical and mechanical durability, making it ideal for tough sample matrices.
S7 Screw Head with PG13.5 Thread Compatibility: The universal S7 screw cap simplifies replacement and cleaning, while the PG13.5 thread enables easy mounting into flow-through or inline electrode holders.
