The aim of this invention is to use an integrated spectral system for measuring response through new style in terms of the absorption cell, irradiation sources, sensors used in continuous injection. The entire system is used in the technique of continuous injection by measuring the residual light (light transmission) from a source of irradiation to the cell with a 2 mm path. The technique used in this system is the use of four sources of irradiation, and here came the naming of 4S (four sources) each two of them with angle 90 ° with other sources and with the two adjacent sides of a piece of metal of  Albras with dimensions of 20 × 20 × 40 mm and sensors placed in the opposite two-sided, namely two perpendicular. Hence came the label 2DV namely, two sensors (two Detector Verticle) at the center of the metal piece there is a hole connecting  the irradiation ports and censoring cells  passing the  metal piece center so that the irradiation of any source does not affect the irradiation of the second side and this will be explained in the content. The entire system is protected from external and scatter light whatever the source through   dark and opaque tapes and silicon materials to ensure the absence of any response in the case of work (or lack  when the device is in operating condition). The entire system has been subjected to check the type and rate of response, sensitivity of response and flexibility and ease of work .The results were compared with a spectral device manufactured in the United States by an old company and have a long tradition in this area. Selected wavelengths are: 470 nm (blue) is used to absorb red fluids , 525 nm (green) to absorb pink fluids  and 605 nm (orange)  for the faint blue fluids  and 635 nm (red) for dark blue fluids. These wavelengths are within the visible region, two of them are in one aspects of the one -piece body cell ,corresponds to each of these two sources, one sensor. this system is used to estimate the iron (III) by the reaction of iron with thiosinat to give the dark red color, and aspirin through the interaction of aspirin with iron chloride (III) to give the complex a maroon color also wavelength 605 nm is used to estimate the drug promethazine (Promethazine) interacting with per sulfate sodium while the wavelength 635 nm was used to estimate the dichromate by configuring the complex fast disintegrating Cro5. the obtained results are compared  with measuring  devices of  world-class companies, it was noted that it was  not the best in terms of range, convenience and user license thei as well as being the subject of identicality  and repetition. It  outweigh all of the devices.
