Our Online Optical Dissolved Oxygen Sensor sensor uses advanced fluorescence technology for dissolved oxygen measurement.
The fluorescent dissolved oxygen (FDO) sensor utilizes fluorescence phase detection technology and proprietary algorithms to detect stable and sensitive changes in oxygen concentration or partial pressure. This sensor, which measures the lifetime of fluorescent molecules and their optical phase offset, offers high measurement accuracy compared to second-generation electrochemical measurement technology.
It's plug-and-play and requires no chemical reagents, making it an ideal choice for water quality testing in industries such as chemical engineering, biopharmaceuticals, nuclear power, sewage and wastewater treatment, and smart aquaculture. The sensor also boasts proprietary sensor membrane manufacturing technology, fluorescence phase detection algorithms, and electronic circuit hardware and software systems.
This sensor is widely used for continuous dissolved oxygen monitoring in sewage treatment processes, water plants, surface water, industrial process water, wastewater treatment, aquaculture and more.
Key Features:
- Proprietary sensor membrane manufacturing process, fluorescence oxygen phase algorithm, and electronic circuit hardware and software systems.
- Widely applicable in various applications (environmental protection, aquaculture, food processing, and other fields).
- Strong anti-interference capabilities.
- Low maintenance, long lifespan, and a long service life.
Ordering Notes:
1. All Sper Online Water Quality Meters and Sensors are sold separately - one of each is required for a complete system.
2. All Online Water Quality Meters and Sensors ship direct from the factory. Please allow 10-15 business days for shipping and handling.
