optek’s Saybolt color analyzer is a dual wavelength light absorption sensor. Operationally, the sensor passes a white light beam through the stream to be monitored, where light absorbance is measured at two distinct wavelengths. The measuring wavelength is set to focus on or near the peak absorbance point of the “yellowness” curve, while the secondary wavelength is chosen to compensate for any influence due to light scattering (window fouling, particulate, immiscible fluids, gas bubbles, etc.). Together, the sensor yields a repeatable and reliable true color number without any sample conditioning.
