Inline Industrial Polarographic Dissolved Oxygen Sensor
The Inline Industrial Polarographic Dissolved Oxygen Sensor features a significant upgrade from previous models, incorporating a grit mesh metal membrane instead of a traditional diaphragm.
This enhancement provides increased stability and stress resistance, making it well-suited for harsher environments. It requires less maintenance and is ideal for continuous dissolved oxygen measurement in applications such as urban sewage treatment, industrial wastewater management, aquaculture and environmental monitoring.
Key Features:
- Enhanced design with a grit mesh metal membrane for superior stability and stress resistance.
- Suitable for challenging environments with reduced maintenance needs.
- Ideal for continuous monitoring of dissolved oxygen in urban sewage, industrial wastewater treatment, aquaculture, and environmental monitoring.
Ordering Notes:
1. All Sper Inline Water Quality Meters and Sensors are sold separately - one of each is required for a complete system.Â
2. All Inline water Quality Meters and Sensors ship direct from the factory, and have a 10 day lead time for shipping.Â
