Spectral Measurement, Online

Xylem Analytics South Asia offers WTW range of innovative online Spectral Measurement technique for reagent-free measurement directly in the process – NO2, NO3, COD, TOC, DOC, BOD, SAC, UVT and TSS. The optical method of these sensors enables a continuous measurement of carbon-and nitrogen-parameters directly in the medium. For simultaneous measurement of several parameters the information of the whole spectrum is evaluated during the process. At the same time cross-sensitivities of single parameters and interferences such as turbidity are eliminated. Easy handling: no sample taking and preparation; no reaction times; minimal cleaning efforts. Minimal operational costs: no routine service necessary; no use of reagents; no spare parts such as wiper; integrated, maintenance-free ultrasonic cleaning. The integrated ultrasonic source induces oscillation of the measurement windows. The resulting movement of the surface prevents the attachment of dirt and fouling right from the start. This guarantees comparable and reliable measuring results during continuous operation. Robust materials such as titanium peek down to the last screw; integrated shock protection; usage even in corrosive media. High measuring accuracy: continuous measurement directly in the process; optimised referencing for excellent zero point and long term stability; and compensation of interferences by evaluation of the whole measured spectrum.
