One of its main advantages is its operation comfort and its safe handling thanks to ergonomic and compact design. Luminous source are LEDs with high long-run constancy and monochromatic light spending at low power input.
The measuring principle is the photometric method, e.g. the DPD method using fluid reagants according to the German standard DIN 38 408. The big advantage of Photometers against comparators: the light conditions to measure the sample are invariable, this granting higher accuracy and minimizing the chance of subjective errors.
