Online COD Water Quality Analysis Sensor with RS485 Professional Integrated
COD Intelligent sonde adopts RS485 communication port and standard Modbus protocol with cleaning brush.
Description
COD Intelligent sonde adopts RS485 communication port and standard Modbus protocol with cleaning brush. At the same time, the absorbance of water at 254nm and 546nm can be measured, and it can be converted into COD, BOD, TOC, etc. to quickly reflect the changes of water.
Based on the coherent detection technology, the sonde has the advantages of high accuracy, good stability, strong anti-interference, no preprocessing and fast measurement.Double beam measurement can effectively reduce turbidity interference. With self-cleaning brush to avoid attachments.Attached with data analysis software, with calibration, recording, analysis, diagnosis and other functions.
Application
Widely used in small water, surface water, river section, lakes and reservoirs, municipal sewage, sewage treatment, seawater monitoring
Feature
● The coherence detection technology has good precision and stability
● No chemical reagents, no secondary pollution, rapid measurement
● With self-cleaning function, it can remove the attachment in water sample, free from maintenance
