ECO NTU
WET Labs offers the Environmental Characterization Optics (ECO) series of meters that incorporate a common set of options with a single basic design to make them ideal for a wide variety of deployments. The NTU provides:
● Unparalleled sensitivity of the ECO in an optical scattering measurement at 660 nm for determining turbidity.
● Turbidity measurement data that is not affected by CDOM concentration, unlike instruments that attempt to measure turbidity by using blue wavelengths.
● The option of analog output for easy integration into CTD packages.
● Excellent precision, reliability and overall performance at a fraction of the cost and size of similar instruments.
