DIT-M, DIT-L, DIT-IR 1 Fig. 1 DIT-M photometer The DIT photometer is a measuring device combining the mobility of a portable photometer with the characteristics of a laboratory photometer. The high level of accuracy of the Grundfos reagents and the user-friendly nature of the photometer guarantee rapid and reliable analysis of up to 14 parameters in water treatment applications. DIT-M operates with six interference filters and uses six long-life LEDs as a light source. No moving parts are involved. Measurement takes place in a transparent measurement chamber. Tablet reagents with a...

DIT-M, DIT-L, DIT-IR 2 Functions 2. Functions Photometric measuring principle When adding specific reagents to a water sample, the sample takes on a degree of coloration proportional to the substance being analysed. A LED emits a light beam with the wavelength (colour) needed for analysing the substance. The sample absorbs a part of this light beam, in proportion to the concentration of the substance being analysed. The photosensor measures the remaining light quantity. The photometer calculates the corresponding concentration of the substance in the sample accordingly. LED Fig. 4 Sample...
