Inline dO2 Sensors
Metroglas dissolved oxygen sensors are low maintenance and provide reliable results over a broad measurement range—from 100 ppm up to 100% oxygen saturation. The inline amperometric as well as optical DO sensor are created to high hygienic standards and withstands both clean-in-place (CIP) and sterilize-in-place (SIP) procedures.
Designed mainly for situations like monitoring cell cultures, these inline DO sensors can also be used for various other applications, e.g., drinking water, wastewater, fermentation broths, beer, wine, and fruit juice production, and more. Extremely suitable for applications in the pharmaceutical and biotechnological industries.
Key Benefits
- Stable measurement signal over the entire application time due to low drift and short response time
- Sustainable performance over entire sensor lifetime even with regular CIP or SIP cycles
- Reliable measurement results with the optimized design and proven materials
