Measurement Principle

　　The water sample is mixed with the conditioner after acid digestion, then oxidized by the oxidizer, and in the alkaline environment and the presence of the indicator, it reacts with the indicator to generate a colorful complex, and the analyzer detects the change of this color and converts this change into the total zinc value output. The amount of colorful complex generated is equivalent to the total amount of zinc.

Main Features

　　Touch screen display and command input; multiple sampling and measurement modes, unique design, lower failure rate, lower maintenance, lower reagent consumption and higher cost performance.
