OBS-3+ and OBS300 Suspended Solids and Turbidity Monitors

sediment, plankton, bacteria and viruses, organic acids, and dyes. In general,

as the concentration of suspended matter increases, so will water turbidity, and

as the concentration of dissolved light-absorbing matter increases, turbidity

will decrease.

Turbidity (operational definition): NTU value is a number ranging from 0 to

10,000 that is computed by a turbidimeter from measurements of the intensity

of light scattered from water sample and by interpolation between bracketing

SDVB (AMCO Clear

) calibration values.
