• 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.
