The Pyxis LT-63X Series Self-Wiping & Submersible Turbidity Sensors are submersible, waterproof, self-cleaning sensors that utilize dual wavelength detection technology to measure turbidity in the ranges of 0 to 4000 NTU. The sensor automatically compensates for disturbances caused by flow fluctuations, climate change, color change or changes in turbidity. The instrument design is virtually maintenance-free, and the self-cleaning capability of the sensor prevents deviations caused by air bubbles and suspended solids particulate.
