Online RS485 Interface Dissolved Oxygen Meter For Water Quality Monitoring

 
Online RS485 Interface Dissolved Oxygen Meter For Water Quality Monitoring

Dissolved oxygen, Usually recorded as DO. Expressed in milligrams of oxygen per liter of water, mg/L.
 
The content of dissolved oxygen in water is closely related to the partial pressure of oxygen in the air and the temperature of water. The lower the water temperature, the higher the dissolved oxygen content in the water.

Dissolved oxygen value is a basis for studying the self-purification ability of water. The dissolved oxygen in the water is consumed, and it takes a short time to restore to the initial state, indicating that the water body has strong self-purification ability, or the water body is not seriously polluted. Otherwise, it means that the water body is seriously polluted, the self-purification ability is weak, or even loses the self-purification ability.

FAQ
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 functi​on? 
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.
 
5. Does the dissolved oxygen controller have an ambient temperature alarm function?
Our DO controller has ambient temperature alarm function
