Hexavalent Chromium Online Water Quality Analyzer
>>Overview
>>Principle
The product utilizes the diphenylcarbazide spectrophotometric method for hexavalent chromium detection. After mixing the water sample with conditioning agents, Cr⁶⁺ reacts with the indicator in an acidic environment to form a colored complex. The monitor detects the color intensity change at specific wavelengths, converts it into Cr⁶⁺ concentration values, and outputs the results. The amount of colored complex generated is proportional to the hexavalent chromium concentration.
