The principle of photometry
When specific reagents are added, the water sample takes on a degree of coloration that is prportional to the concentration of the parameter being measured. The photometer measures this coloration.
When a light beam passes through the coloured sample, energy with a specific wavelength is absorbed by the test substance. The photometer determines the coloration of the sample by measuring the transmission or absorption of light of this wavelength (i other words, monochromatic light). The photometer then uses a microprocessor to calculate the required concentration and displays the result.
