The LY-5034 Fully Automatic CODcr Analyzer is a professional intelligent analytical instrument specially developed for the determination of chemical oxygen demand (CODcr value) in various water samples. Based on the standard dichromate method, it is designed for environmental supervision agencies, industrial wastewater treatment facilities, municipal water treatment plants and third-party testing institutions, delivering high-precision, high-repeatability and high-throughput CODcr detection services. The instrument fully automates the entire testing process from sample addition to data calculation, effectively reducing manual operation errors and improving the efficiency of batch water quality testing.
The LY-5034 Fully Automatic CODcr Analyzer strictly follows the classic CODcr detection principle: adding a known amount of potassium dichromate solution to the water sample, using silver salt as a catalyst in a strong acid medium, boiling under reflux, then titrating the unreacted potassium dichromate with ammonium ferrous sulfate using ferroin as an indicator, and finally calculating the oxygen consumption mass concentration according to the consumed potassium dichromate amount. The test results are fully consistent with standard methods, with high authority and traceability.
Equipped with a 40-position sample tray, the instrument realizes fully automatic processing of batch samples, completing the whole process of digestion, titration, data calculation and result output without manual intervention, which greatly improves the detection efficiency of professional laboratories and industrial water treatment facilities.
It adopts advanced RGB color recognition technology to achieve accurate judgment of titration end point, effectively avoiding the visual error of manual titration, ensuring the repeatability and accuracy of test results, and providing reliable data support for compliance discharge and regulatory law enforcement.
The instrument is equipped with an intelligent touch screen interface, supporting intuitive operation and remote monitoring. With high-reliability structural design, it has a long maintenance cycle, and we provide complete operation and maintenance training and manuals for users, greatly reducing the difficulty of daily operation and maintenance.
The LY-5034 Fully Automatic CODcr Analyzer fully complies with the relevant water quality 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 CPA certification (China Environmental Protection Product Certification), ensuring that the test data can be used for regulatory law enforcement, compliance discharge certification and authoritative test report issuance.
