Product Introduction
The ESN1000 Dissolved Oxygen Analyzer is a professional instrument used to measure the dissolved oxygen concentration in water. It adopts the principle of the fluorescence method. Its core function is to detect the content of free oxygen molecules in water, so as to evaluate the self-purification capacity of water, biological activity, or the effect of process control.
Instrument Features
- High precision and stability;
- No oxygen consumption;
- Resistant to pollution and easy to clean;
- Fluorescent membrane cap, no electrolyte required, and basically no maintenance needed;
- Digital sensor with strong anti-interference ability;
- Real-time monitoring with fast response;
- Supports immersion and pipeline installation.
Typical Applications
Sewage treatment plant aeration tanks, power plant water treatment, water environment monitoring, aquaculture, food and chemical industries.
