Chroma Meter
The CR-121's illuminating stem, using 45/0 geometry, is
identical to that used by densitometers in the printing industry, allowing
users to measure color from printed matter and other gloss surfaces. In
addition, its 3mm diameter measuring area enables precise targeting for
spot color readings.
Main Features
- Precise readings with high repeatability
- Lightweight and battery powered readings displayed in
Yxy or L*a* b* color space
- Built-in memory for measuring color difference
- Choice of calibration standards
- Choice of two illuminants
- Efficient, consistent illumination
- Illumination monitoring system
- Interfacing with peripheral units
Application
- Manufacturing: Color control of painted and coated
surfaces
- Printing: Control of color density, ink
characteristics, etc.
Illuminating System
Light from the pulsed xenon arc lamp is diffused in the
mixing chamber and projected onto the sample at a controlled angle of 45°.The light reflected vertically from the sample is collected by the
optical cable and sent to the silicon photocells for color evaluation.
