Shenzhen Shengkian SKA13-18118745715 water quality testing instrument

Potassium permanganate index analyzer

1. product description

Environmental Protection Potassium Permanganate Index Analyzer uses "potassium permanganate + spectrophotometry" to detect the permanganate index in surface water,groundwater,drinking water and environmental water. Compared with analyzers using "potentiometric titration",this instrument has more advantages in measurement stability,maintenance convenience,price and operation and maintenance costs.

Advanced "automatic sampling and dose measurement" and "sampling process" technologies,combined with optimized reagent formulas,and powerful abnormality self-checking and repair capabilities,truly realize on-site analysis and detection,which is convenient,fast,accurate and efficient,and users do not need to retrieve it. Laboratories perform tedious testing. At present,the acid method is mostly used for online monitoring of surface water,groundwater,drinking water and other water quality,while the alkali method is mainly used for testing in saline waters,coastal waters and coastal waters.

1. Performance parameters

1. Technical advantages

(1) Use "automatic sampling and dose measurement" technology to further improve the accuracy of sampling and ensure the accuracy of test data;

(2) Optimize the reagent formula to avoid unnecessary waste of reagents while improving measurement stability;

(3) Spectrophotometry is superior to "potentiometric titration" in terms of stability,maintenance and operation and maintenance costs;

(4) Use backlight compensation measures to avoid the problem of unstable measurement of LED output light caused by temperature effects;

(5) "Touch screen + signal board + expansion board" architecture and rich expansion interfaces facilitate user secondary development and integration;

(5) Support users to customize personalized products according to their own needs;

(6) Apply foreign advanced and mature technologies and select mainstream products widely used in engineering,whose technical performance is at the leading level of similar products;

(7) Through program control,instrument power outage protection and automatic pipeline cleaning and measurement recovery can be realized when power comes in.

1. working principle

Under acidic/alkaline and heating conditions,potassium permanganate oxidizes certain organic and inorganic reducing substances in the sample. After the reaction,excess sodium oxalate is added to reduce the potassium permanganate,and then a known amount of high The potassium manganate standard solution oxidizes the sodium oxalate; measure the absorbance of the potassium permanganate at a wavelength of 525 nm and convert it into the corresponding permanganate index.

1. Instrument design principles

2. Advanced and mature technology:Apply foreign advanced and mature technology and select mainstream products widely used in engineering. Their technical performance is at the leading level of similar products. In terms of system integration,equipment selection and configuration,we fully consider the reasonable matching and connection methods between various accessories and systems,and strive to optimize system integration.

3. Standardity:The standardization of the structure,when pl the system structure,adopts the layout and structure that conforms to international standards,the foundation for system integration and application development.

4. Operability:Ensure that the analyzer is user-friendly and operable,making it easy for users to understand,learn,master and use the human-computer interface and provide a graphical human-computer interaction interface.

(4) Safe and reliable:The equipment,equipment and components used in the analyzer are all products that have passed international certification or have been tested by my country's relevant product quality inspection center,allowing the instrument to operate efficiently,reliably,safely and smoothly.

(5) Easy to manage and maintain:The selected equipment,components,and electronic components are standardized to facilitate management and maintenance.

(6) Economy:The entire instrument must not only use advanced domestic and foreign products as much as possible,but also be reasonably matched to reduce redundancy and cost. On the premise of meeting the needs of the instrument,cheap equipment should be selected as much as possible to save investment,that is,equipment with excellent performance-price ratio should be selected.

(7) Flexibility:The design of the analyzer should adopt a modular structure,requiring flexible hardware configuration,convenient software organization,and easy system expansion.
