Abstract
The present invention relates to a device for measuring both the color and turbidity of a liquid sample. LEDs are used as light sources and reference detectors are included to control the output of the LEDs. The device is also capable of monitoring and correcting for fouling of optical surfaces. The device is intended to be installed in-line in a mains water supply line. The device can be used in domestic water meters or on sewage treatment sites to monitor the effluent discharged back to the river.
