The turbidity and pH measurement are the most important factors that determine the purity of the user to drink properties. The modern method to monitor pollutants in the water is the use of multi-mode optical fiber, where we depend on the intensity modulation of light passing through the water sample. Use of Bear Lambert relationship, for the purpose for calculating the attenuation and the concentration of pollutants suspended in the water, through the creation and design of plastic cell with openings to let water in and out, and proves inside the optical fiber without cover and with fixed length. We can calculate the transmission and absorption with draw a relationship between the transmissions or absorption with the pH values or turbidity concentration. The calibration curve was obtained, when drawing this relationship.
