HLZn1-1 typeZinc water qualityOnline monitoring analyzer

Working Principle:AtIn an aqueous solution with a pH of 4.0-5.5, zinc ions form a red chelate with dithizone, causing a change in the color of the mixture. The degree of color change in the solution is proportional to the zinc content in the water sample, and the zinc value of the water sample can be calculated by colorimetry.

Performance parameters:test scope （0.1-50) mg/L has automatic range switching function, which can achieve automatic measurement of water samples with different concentrations.
