1. Which sensors can be connected to your dissolved oxygen controller?
A: The dissolved oxygen meter can be compatible with DRFN digital dissolved oxygen sensors including fluorescence and polarography.
2. How does your DO controller collect sensor data?
A: The connected sensor uploads the detected data in a special encrypted communication method to ensure that the DUC controller can collect high-precision data more stably
3. What are the applications of dissolved oxygen analyzers?
A: Sewage/Surface water monitoring/Aquaculture water bodies/Urban sewage treatment/Industrial wastewater treatment /Aquariums
4.Can the dissolved oxygen controller realize the automatic cleaning control function?
The DO controller has a self-cleaning control function, and Our DO sensor has a cleaning interface.
The end customer can choose water or air, Realize automatic cleaning. But the end user need to buy a solenoid valve himself.
