Online OTA RS485 Interface Dissolved Oxygen Analyzer For Industry Water Monitoring

 
Online OTA RS485 Interface Dissolved Oxygen Meter For Industry Water Monitoring

Common applications for dissolved oxygen meter:
 

1. Aquaculture:

Guarantee the breathing needs of aquatic organisms, real-time monitoring of oxygen content, automatic alarm, automatic oxygenation and other functions.

2. Water quality monitoring in natural waters
 

Detect the pollution degree and self-purification ability of water bodies, and prevent biological pollution such as eutrophication of water bodies.
 

Therefore, the most prominent feature of the HART protocol is that digital communication is compatible with analog signals of 4 to 20 mA, and the transmitted signal is superimposed on the analog signal of 4 to 20 mA with a modulated sinusoidal signal.

3. Sewage treatment, control indicators
Anaerobic tank, aerobic tank, aeration tank and other indicators are used to control the effect of water treatment.

4. Control the corrosion of metal materials in industrial water supply pipes
Generally, a sensor with a ppb (ug/L) level range is used to control the inside of the pipeline to achieve zero oxygen to prevent rust. It is often used in power plants and boiler equipment.

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
