Choose the 890nm infrared LED as the light source after compared the capabilities of incandescent lamp/tungstic lamp and LED/LD and also think about the selective absorbability of water; it has strong points such as constant light intensity,long life, narrow light spectrum,etc, and use the infrared light with 890nm wavelength to decrease the influence of optical-absorption matters.Choose the photosensitive diode which suitable to the LED which we choosed after compare the capabilities of light sensitive resistor, photocell, photosensitive diode and phototriode. Both of these make up the photoelectric system of turbidimeter.
