The HH SCIENCE HH2800 pH electrode is purpose-built for high-temperature and high-pressure process environments, delivering stable and accurate pH measurement in conditions that exceed the limits of conventional sensors. It features a high-temperature (HT) glass membrane and high-temp synthetic gel electrolyte, both rated for continuous exposure to temperatures as high as 150°C.
Internally, the HH2800 incorporates a dual-junction reference system, providing superior resistance to contamination and electrolyte poisoning—critical for media with organic loads, reactive ions, or cleaning agents. The design is fully compatible with CIP (Clean-in-Place) and SIP (Sterilization-in-Place) protocols, as well as autoclaving up to 140°C, enabling the electrode to perform reliably over 30+ fermentation or batch sterilization cycles.
With its IP68 waterproof rating, reinforced membrane structure, and exceptional chemical compatibility, the HH2800 is the professional choice for biopharma, food-grade, chlor-alkali, and petrochemical process monitoring under extreme thermal conditions.
Key Features
- Exceptional High-Temperature Resistance: All sensor components are rated for continuous operation up to 150°C, withstanding harsh thermal shocks and sterilization procedures.
