The DH334DS multi parameter water quality online analyzer is a conventional five parameter water quality online monitoring instrument, which includes pH, temperature, dissolved oxygen, conductivity, and turbidity. The monitoring instrument adopts a modular design, with the analyzer host connected to four sensors including pH, dissolved oxygen, conductivity, and turbidity. The conventional five parameters of water quality can directly and comprehensively reflect the degree of organic and inorganic pollution in the water body as well as some related physical indicators of the water body itself. The conventional five parameters are also listed as mandatory items in the monitoring projects of the National Environmental Protection Administration.
Integrating data collection, processing, and transmission, with high reliability and low cost;
Simultaneously connect 4 sensors and measure 5 parameters, and display multiple sets of test values simultaneously;
Less movable parts, modular design, easy installation and maintenance, improve instrument efficiency;
Adopting digital filtering and slip technology to intelligently improve the response speed of instruments and the accuracy of measurement data;
The instrument circuit board adopts SMT surface mount technology to improve the reliability of product processing.
