Zinc Online Water Quality Analyzer
>>Overview
>>Principle
The product employs the spectrophotometric method for zinc detection. After mixing the water sample with a conditioning agent, all forms of zinc are converted to zinc ions (Zn²⁺). In an alkaline environment and in the presence of a sensitizer, Zn²⁺ reacts with an indicator to form a colored complex. The analyzer detects this color intensity change, converts it into zinc concentration values, and outputs the results. The amount of colored complex generated corresponds to the total zinc concentration.
