The LISA-Colour sensor is based on the same concept of the more expensive TriOS sensors such as OPUS and VIPER but uses the latest UV LED technology to photometrically report the UVT and inferred TOC/COD/BOD concentration in water and waste water. The two detection channels enable a precise optical determination of colour by absorption. Different path lengths accommodate a wide range of measurement which is particularly important for colour measurement requring a long path length for precise analysis. Automatic compressed air cleaning may be simply integrated. Alternatively, an automatic wiper system may be simply attached. Typically, the sensor is directly immersed in the sample channel. Options are available for flow cell installation with optional ultrasonic cleaning or sample break tank installation. The robust stainless steel housing may be upgraded to a titanium construction for saline applications. The sensor may be connected to the Tribox mini or Tribox 3 controller of used as a blind sensor with a G2 interface. The sensor is ideal for water production monitoring applications such as intake protection or waste water process control and compliance monitoring.
