Konica Minolta CM-25d Spectrophotometer Built With d:8° Geometry And Horizontal Alignment

The CM-25d spectrophotometer is the successor to CM-2500d built with single aperture MAV  capable to deliver both measurement data including (SCI) and excluding (SCE) surface condition simultaneously at ultra-high speed. The symmetrical and compact design, allows measurement of hard-to-reach areas like vehicle interior.

CM-25d spectrophotometer were developed to true “Digital Color Data Management” to help minimize the need of physical samples within a supply chain.  With tight inter-instrument agreement levels of  ∆E*ab< 0.2 and high repeatability of σ∆E*ab 0.04  the CM-25d ensures measurement data communicated within a supply chain remain consistent.

It has a viewing observation port allows perfect sample positioning for measurements and the large color LCD display shows measurement data either numerically or graphically. 

The CM-25d comes with the Configuration Tool CM-CT1 software (standard accessory) that allows user to not only create/write instrument settings, but also compiling it into a file and share it within its supply chain.
