Abstract:
A photometric measuring system, comprising a holder (2) provided with at least one storage chamber (4) for holding a fluid to be measured, at least light generator (6) for generating a light beam (8) to interact with the fluid in the storage chamber (4) and at least one light detector (14) for detecting, during operation, at least a portion of the light which has interacted with the fluid present in the storage chamber (4), in which system at least a portion of the walls of the storage chamber (4) has been provided with a reflective surface (20) so that at least a portion of the light which has entered the storage chamber (4) will be reflected and detected by the detector (14), characterized in that, in order to realize a photometric measurement which can be carried out with respect to the fluid in the storage chamber (4) independent of the wavelength of the generated light beam (8), each storage chamber (4) has an upper open end and the generator (6) as well as the detector (14) can be arranged at a predetermined distance above said upper open end, such that the light and the light path between the light generator (6) and the detector (14) does not meet any physical window.
