Comparator 3000 Series
Introduction
The Lovibond®Comparator 3000 Series instruments are single scale
3-field instruments used for visual grading to determine the colour of a
sample, achieved by direct comparison of Lovibond®Glass Standards and
the liquid sample.
To achieve rapid colour grading within pre-determined colour limits, the
glass standards are mounted in two discs so that it is easy to check that
the sample is within tolerance.
The two discs containing the relevant colour scale are brought together
by a prism and viewed simultaneously alongside the sample making it
easier to achieve an optimum match.
When seen through the prism, the sample is viewed in the centre. The
colour standards are viewed either side of the sample, as in the following
diagram:
The human eye perceives colour differently according to the lighting
conditions, so constant lighting conditions are essential for consistent
colour comparison. The Comparator 3000 Series uses a tungsten halogen
lamp which is colour corrected to CIE standard Illuminant C to produce a
consistent light source.

Information
Permanent Colour Glass Standards
The colour standards for use with the Comparator 3000 Series consist of
flat chemically produced glass. Unlike plastics, Lovibond®permanently
coloured glass standards are guaranteed not to fade with continuous
exposure to daylight and will give reliable accurate results every time.
The standards are mounted into a disc which is easily positioned in the
Comparator 3000 Series.
Special Disc Service
The Tintometer Ltd. is able to produced customised glass standards to
suit your requirements, for special chemical and colorimetric analysis.
The Company has great experience in the development of such standards,
and they are manufactured in accordance with the procedures required
by The Tintometer Ltd’s ISO 9001 certification.
The standards are mounted in a disc for use with the Lovibond®
Comparator 3000 Series.

Note: The best colour match is obtained by viewing with one eye closed
Rotate the discs by turning the knobs on the front of the instrument until
the oil sample matches or falls between two Colour Standards. A reading
can then be taken from the disc.
FAC / EBC:- To change the disc pair: open the lid, pull the knobs and lift
out the discs. To insert the discs: pull the knobs, insert the discs and
rotate the knobs until they engage in the discs.
