Dissolved Oxygen Sensor Oxygen Probe Sensor Supplier
Product Overview
- Model DOG-208FA is a high-technology dissolved oxygen (DO) electrode / probe designed for reliable DO and temperature measurement in liquids and gases.
- It is built for continuous online use and specifically engineered to withstand steam sterilization up to 130 °C and to operate with pressure auto-balance capability.
- Typical sizes: electrode diameters 12 mm or 25 mm and insertion lengths 120, 225 or 325 mm.
Product Features
- Measurement: DO range 0–20.0 mg/L (also notes 0–100 μg/L) and temperature up to 130.0 °C; stated DO accuracy ±0.1 (as provided).
- Construction: SS316L body, fluorine-plastic/silicone/stainless-steel-mesh composite permeable membrane, platinum cathode and silver anode, PT1000 temperature compensation.
- Performance: response current ≈60 nA in air,
- Principle: polarographic-type high-temperature electrode; breathable membrane head for robust operation in pharma/biotech processes.
Product Value
- Provides accurate, stable DO readings under high-temperature sterilization and autoclave cycles, enabling reliable process control in sterile and high-temperature environments.
- Minimizes measurement downtime and sensor replacement costs by tolerating repeated sterilization and pressure changes.
- Supports regulatory and production quality needs in pharmaceutical, biotech, fermentation and brewing operations through traceable, continuous monitoring.
Product Advantages
- High-temperature resistance (up to 130 °C) and pressure auto-balance design for direct use in steam-sterilized systems.
- Durable materials (SS316L, composite membrane, steel gauze) for long-term stability and physical robustness.
- Fast response, low drift and low background current for precise monitoring; compatible as a direct replacement for some METTLER TOLEDO and Hamilton high-temp DO sensors.
- Backed by BOQU’s production capability, service network and export experience.
Application Scenarios
- Online DO monitoring in small microbial culture reactors and laboratory fermenters.
- Pharmaceutical and biotech process control where steam sterilization/autoclaving and CIP cycles are common.
- Brewing and fermentation processes, sterile liquid processing lines, and any high-temperature or high-pressure DO measurement needs in R&D and production.
