LT6900 130°C High-Temp Dissolved Oxygen Sensor for Fermentation

Ideal for industrial procurement, the LT6900 130°C high-temperature dissolved oxygen sensor features 316L stainless steel for stable fermentation steam sterilization.

● 130°C Steam Sterilization Capability: Designed for demanding CIP (Clean-In-Place) and SIP (Sterilize-In-Place) processes, the LT6900 safely withstands repeated in-situ steam disinfection and pressure cooker sterilization up to 130°C.
● Sanitary 316L Stainless Steel Construction: Features an ultra-smooth, full 316L stainless steel body that meets strict food, beverage, and pharmaceutical hygiene requirements, effectively preventing media contamination during operation.
● Extended Fermentation Lifespan: Equipped with a premium, imported high-quality membrane cap that maintains exceptional measurement stability under high temperature and pressure, easily enduring over 40 intensive fermentation batches.
● Compact Design for Limited Space: Specifically engineered for bio-reactors and containers with small volumes. It utilizes a robust VP connector and offers highly customizable insertion depths and cable extensions up to 30 meters for flexible industrial integration. It serves as a seamless, cost-effective replacement for Mettler Toledo or Hamilton DO sensors in bioreactors.

Sanitary High-Temp DO Sensor Core Features

Engineered for biotechnology and pharmaceutical manufacturers, the LT6900 is an advanced 130°C High-Temp Dissolved Oxygen Sensor for Fermentation. This robust probe features a sanitary full 316L stainless steel body and an imported high-quality membrane, allowing it to safely withstand rigorous CIP/SIP steam sterilization up to 130°C. Perfect for small-volume bioreactors, it ensures zero contamination while maintaining peak accuracy (<± 0.3mg/L) for over 40 intensive batch cycles, it seamlessly replaces expensive European sensors in small-volume bioreactors. Boasting a standard 120mm insertion depth, PG13.5 thread, and VP4 connection, it provides procurement managers with a highly reliable, space-saving solution for food, beverage, and cell culture optimization.
