UV Optical Technology for optimal measurements of COD, BOD, TSS, TOC
The StacSense probe uses UV absorption at 254 nm to measure organic compounds dissolved in water. This absorbance is correlated with the concentration of TOC, COD and BOD to provide a high-performance probe requiring no consumables.
A reference measurement at 530 nm is used to compensate for the presence of particles in the sample that also absorb UV light and to establish the Turbidity parameter.
The use of a state-of-the-art high-performance UV LED, combined with rigorous ignition management, offers an optimal variance of the signal
