User Guide

• Press the READ/ key and the LCD will display a blinking “SIP” (Sampling

In Progress). The limpidity value will appear after approximately 25 seconds.

SOURCES OF INTERFERENCE

• Presence of floating debris and coarse sediment which settle out rapidly will give

false readings.

• The infrared light source used for C125 limpidity meter can effectively minimize

errors due to coloured dissolved substances. This effect, named “true colour”,

is a common interference for most commercially available instruments operating

in the range of visible light.

• Air bubbles and the effect of vibrations that disturb the surface of the sample

will give false results.

• Dirty glassware could also affect readings along with scratched or edged cuvette.
