Konica Minolta CM-25cG User manual

The new standard instrument for Automotive Interior
materials
Spectrophotometer
CM-25cG
A 2 - in - 1 instrument for measuring
Colour & Gloss simultaneously
Ready for Digital Colour Data Management
Enhanced form and functions to
measure interior trims and materials

The CM-25cG is a portable spectrophotometer with
45°c:0° geometry and a true high-performance 60°
gloss-sensor. With no compromises in performance,
the CM-25cG has been designed to match or exceed
standards for colour and gloss measurement in a
number of industries, including automotive interior
materials and high visibility textiles (EN471) or coatings.
The perfect circular optical system (45°c:0°) achieves
high accuracy and repeatability, especially on textured
or structured surfaces, regardless of measurement
direction.
CM-25cG
Maximum versatility and industry best
accuracy levels for Automotive Interiors
A 2 - in - 1 spectrophotometer for
simultaneous colour & gloss measurements
A compact handheld spectrophotometer with 45°c:0° geometry and high performance 60° gloss sensor for
simultaneous colour and gloss measurements of automotive interior trims and materials with a number of
“world rst” features.
Unprecedented Inter - Instrument -
and Inter - Model - Agreement
The CM-25cG was developed in close cooperation
with major car makers with the aim, to reduce the
exchange of physical samples with suppliers while at
the same time keeping historical data, to allow the
user to communicate measurement data based on
absolute values enabling true “Digital Colour Data
Management” throughout the value chain.
Consequently, all CM-25cG are true Close Tolerance
(CT) grade instruments, and thus Konica Minolta once
again proves its unsurpassed ability and expertise
in optical precision technology. Highest Inter-Instru-
ment- Agreement (IIA) levels of just ∆E*ab 0.15 and
the same for Inter-Model-Agreement (IMA) with the
previous model dene an unprecedented level of per-
formance.

Spectrophotometer
With its lightweight, sleek and ergonomic design,
extremely fast measurement speed of just 1 second
and optional Bluetooth®wireless data communication,
the CM-25cG is perfectly suited for use in a production
environment. Sample viewing port and measurement
buttons on both sides of the body enhance usability
under all conditions.
Changeable apertures for medium and small size
allow colour and gloss measurement of small and
even curved samples – another world rst!
Colour: ø 8mm / ø 3mm
Gloss: ø 10mm / ø 3mm
Enhanced form and functions for
Automotive Interior Materials
The CM-25cG has a built-in 2.7” color LCD allowing
measurement values to be evaluated numerically and
graphically or just as a PASS/FAIL message against a
dened standard.
