The LY-5032 Automatic Permanganate Index Analyzer is a professional, high-throughput analytical instrument purpose-built for accurate determination of permanganate index (CODₘₙ value) in aqueous samples. Based on the classic redox titration principle, it uses potassium permanganate to oxidize reducing substances in acidic/alkaline solutions, then back-titrates excess potassium permanganate with sodium oxalate standard solution, with results directly quantified by potassium permanganate consumption. Designed for professional industrial users and testing organizations, this analyzer delivers fully automated, high-precision CODₘₙ testing, eliminating manual errors and drastically improving laboratory testing efficiency.
This CODₘₙ water quality analyzer adopts fully integrated automation technology, realizing one-click detection from sample digestion to titration result output, with full unattended operation. The intelligent electronically controlled robotic arm enables stable, high-precision sample cup transfer, high-temperature grasping and titration, completely replacing manual intervention for full-process automation.
Equipped with high-resolution RGB visual sensors simulating human eye recognition, the system automatically judges the titration endpoint via real-time color change monitoring, delivering accurate and reliable endpoint identification with precision RSD ≤ 3.0% (3.0 mg/L glucose standard solution, n=3).
The system features independent metering for 4 types of testing reagents, with real-time reagent consumption monitoring and low-level early warning, ensuring test validity and avoiding invalid experiments caused by reagent shortage.
The built-in data workstation displays a real-time sample position schematic, supporting free sample cancellation, addition or replacement during operation without stopping the process, greatly improving batch testing flexibility.
The LY-5032 automated permanganate index testing system fully complies with relevant monitoring standards and regulations issued by the Ministry of Ecology and Environment of China, as well as applicable international water quality testing standards. It has obtained official CPA certification (China Environmental Protection Product Certification), ensuring test data is legally valid and meets regulatory requirements for environmental supervision and third-party testing.
