Product Description

Principle:

This product adopts zinc reagent spectrophotometry. After the water sample and the regulator are mixed, various forms of zinc are converted into zinc ions. In an alkaline environment and in the presence of a sensitizer, the zinc ions react with the indicator to generate a colored complex. The monitor detects the color change and converts the change into a zinc value for output.
