Online DO Controller

The Online DO (Dissolved Oxygen) Controller offers reliable dissolved oxygen monitoring in real-time. It suits industries like water treatment, aquaculture, and environmental protection. The controller measures dissolved oxygen with a range of 0~20.00 mg/L. It automatically adjusts for temperatures between 0 to 60°C. The device also uses advanced fluorescence quenching technology, which ensures long-term stability and minimal maintenance.

This controller integrates easily into existing systems. It features 4-20mA signal output or RS485 communication. Two groups of normally open relay contacts provide high and low alarm signals. With optocoupler isolation protection, it ensures safe and accurate performance.

Thanks to its optical detection method, this controller avoids interference from pH fluctuations, ammonia nitrogen, and heavy metals. As a result, it delivers precise and stable measurements over time. Components from Italy and Spain enhance the product’s durability. The user-friendly Chinese menu adds convenience.
