Water hardness analyzer / in-line - COLORIMETER
3S-COLORIMETER - Compact on-line colorimetric analyser - Programmable on-line photometer3S Colorimeter makes two measurements during an analysis cycle:
- the first step is the measurement of the raw sample and allow to compensate the colour and the turbidity of the sample and the fouling of the cell
- the second step is the measurement of the sample after color reagent addition and reaction time
The concentration is measured with the absorbance calculated with the difference between the two measurements and with the stored calibration parameters.
