Measuring Cycle

1. Entry of the sample: The sample enters the measuring cell for washing and priming.
2. First measurement (Photometric Zero): An initial measurement is taken of the sample as is.
3. Reagent addition: Reagent is added using the peristaltic pump.
4. Reaction development: The reaction develops through stirring.
5. Colour reading (Absorbance): The colour (absorbance) is read. The differential measurement between the Zero and the Absorbance is processed by the electronic processor and converted into a concentration value, using specific correlation tables developed in our laboratories.
6. Result display and dosing control: The electronic controller displays the measured substance in mg/L and indicates whether or not to activate the dosing components designed to control or correct it.
7. Automatic calibration: The system calibration is performed automatically at each measuring cycle.
