Konica Minolta CM-23d Spectrophotometer

As an entry-level instrument, the CM-23d utilizes the same user interface layout found in our highest-end portable devices. The CM-23d provides robust color and color-difference measurement capabilities for a wide variety of simple and flat samples.

• Single Aperture Instrument: Features a standard 8mm measurement aperture with an integrated viewfinder for effortless sample alignment.

• Simple Mode: Enables quick and easy evaluation of color differences between a target standard and a test sample.

• Optimized Measurement Speed: Approximately 60% faster than its predecessor (CM-2300d) regarding measurement, charging, and data processing times.

• Full Standard Illuminant and Color Index Support: Allows for simultaneous evaluation under two distinct light sources.

• Lithium-ion Battery: Equipped with a removable battery pack, supporting spare battery replacement and external chargers (the battery can also be charged when connected to power via a USB port).
