Memosens COS22D – Optical Dissolved Oxygen Sensor
The Endress+Hauser Memosens COS22D uses luminescence quenching technology to measure dissolved oxygen without consuming oxygen. This enables stable, drift-free measurement with minimal maintenance.
Key Features
- Measuring principle: Optical (luminescence quenching)
- DO range: 0 to 20 mg/l (0 to 200% saturation)
- Accuracy: ±0.1 mg/l
- No oxygen consumption (no flow dependency)
- Memosens digital technology
- Process temperature: 0 to +50 °C
- Process pressure: up to 10 bar
- Minimal maintenance (no electrolyte replacement)
- Compatible with Liquiline CM4xx transmitters
Applications
Wastewater treatment (aeration control), drinking water, aquaculture, fermentation, food and beverage, pharmaceutical, environmental monitoring.
