Based on the characteristics of world water quality and monitoring standards, combined with our own technical advantages, using a modular configuration concept, the electrode method and microcomputer spectrophotometric measurement principle are cleverly combined. The newly launched ET9910 series of data multi-parameter analyzers not only meet the requirements for water quality testing in various outdoor environments but are also suitable for rapid water quality detection during emergencies and routine water parameter measurements in laboratories, allowing users to satisfy their water testing needs with minimal investment. The spectrophotometer is equipped with over 120 built-in application programs and electrode methods, enabling it to measure more than 135 important water quality parameters, widely used in industrial, municipal, environmental protection, educational and other fields for water quality monitoring.
The instrument quickly measures various water parameters with humanized convenient operation, featuring large capacity storage, RS232, USB data interfaces, allowing the storage and management of data to be transmitted to a computer for further analysis, printing, etc. It is suitable for comprehensive water analysis in the field, production sites, and laboratories, as well as rapid water quality measurements.
