Colorimetric technology measures light absorption at specific wavelengths.

Colorimetric technology is suitable for online measurements of heavy metals in water. After adding reagents to the sample, the parameter to measure will built a coloured complex. The intensity of the color is direct proportional to the concentration. The colour absorption is measured by a photometer at a specific wave lenght

The 6-point calibration connects absorptions and concentration. Between calibration points the results will be interpolated.
