Zn Total Zinc Online Analyzer

The Zn Total Zinc Water Quality Auto Analyzer employs the zinc reagent spectrophotometric method to automate the measurement of total zinc in water samples. Under high-temperature and high-pressure conditions, zinc is separated from the sample. In an alkaline medium, zinc ions react with the zinc reagent to form a blue complex, which exhibits stable maximum absorbance at 610 nm. Within a specific concentration range, the absorbance is proportional to the zinc concentration, forming the quantitative basis for online zinc monitoring.

Widely used for monitoring zinc in industrial wastewater, domestic sewage, and surface water.
