Thermometrics Turbidity Sensor TST-10 measures the turbidity (amount of suspended particles) of the wash water in washing machines and dishwashers. An optical sensor for washing machines is a measuring product for a turbid water density or an extraneous matter concentration using the refraction of wavelength between photo transistor and diode. By using an optical transistor and optical diodes, an optical washing machine sensor measures the amount of light coming from the source of the light to the light receiver, in order to calculate water turbidity.
After testing voltage in water (0 NTU), voltage test in water (4000 NTU) (Turbidity level Calibration -> Master NTU standard liquid) (Voltage between No #2 pin and Ground)
