The HH SCIENCE HH6300HT is a high-temperature dissolved oxygen electrode purpose-built for biological, pharmaceutical, and food-grade applications requiring hygienic design and sterilization compatibility. Derived from the proven QL6900 platform, this model excels in CIP (Clean-in-Place), SIP (Sterilization-in-Place), and autoclave processes, maintaining measurement integrity after repeated high-temperature exposure.
With a rugged 316L stainless steel housing, the HH6300HT meets sanitary requirements for contamination-sensitive environments such as fermentation tanks, bioreactors, and laboratory research setups. Its imported high-performance membrane cap provides reliable oxygen permeability and durability under high-temperature and high-pressure conditions, making it suitable for continuous use over 40+ fermentation cycles.
The HH6300HT is especially well-suited for small vessels, sealed containers, and narrow installations in biotechnology and clean-process industries, where sensor durability, compact design, and measurement precision are critical.
Key Features
- Steam Sterilization Compatibility (120–130 °C): Sensor remains stable and fully functional after repeated high-pressure, high-temperature cleaning and disinfection.
- High-Performance Membrane Cap: Uses imported materials to maintain oxygen response and long-term durability under thermal and pressure stress.
- 316L Stainless Steel Body: Fully compliant with hygienic standards, providing excellent chemical resistance and mechanical strength for aseptic environments.
- Compact Design for Confined Spaces: Optimized for bioreactors, fermenters, and laboratory vessels where space is limited.
- Supports Long-Term Operation: Designed to perform reliably over 40+ fermentation or cell culture batches with minimal drift or recalibration.
Optional Upgrades
- Custom Insertion Lengths: Available to accommodate specific reactor or tank designs.
- Multiple Cable Connector Formats: Compatible with VP connectors and other standard interface types for integration with bioprocess control systems.
- Cable Length Extension: Up to 30 meters for flexibility in plant or lab-scale setups.
