The water sample is first digested by acid at high temperature and then mixed with a regulator. The zinc in the sample reacts with the indicator in an acidic environment to form a colored complex. The absorbance of the complex is proportional to the content of zinc ions (total zinc). The analyzer detects changes in color and converts these changes into zinc ion (total zinc) values for output.

This automatic monitor is widely used for monitoring industrial sewage, domestic sewage, Rivers and Lakes, surface water, tap water and other water bodies.
