PRELIMINARY EXAMINATION
C125 has been designed to perform measurements according to the ISO 7027
International Standard.
The instrument functions by passing a beam of infrared light through a vial
containing the sample being measured.
The light source is a High Emission Infrared LED with a wavelength peaking at 890
nm, ensuring that the interference caused by colored samples is minimum.
A sensor, positioned at 90° with respect to the direction of light, detects the amount
of light scattered by the undissolved particles present in the sample.
The microprocessor converts such readings into FTU (=FNU) values.
