product overview

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.
