The NTU (Nephelometric Turbidity Unit) is a unit of measure used
for measuring turbidity in liquids. The measured value can alterna‐
tively be displayed in FNU (Formazine Nephelometric Unit), see
Fig. 26. The conversion is 1:1.
Measured values over 1000 NTU are outside of the measuring
range of this DULCO turb C.
Measured values above 11 NTU, 110 NTU, 1100 NTU cause the
display to flash and a message to be displayed indicating too high
a measured value depending on the measuring range selected.
An arrow is positioned next to
[AUTO] during normal operation of
the DULCO turb C. In this state, the bottom row indicates the unit
of measure and the top row shows the current measured value.
