The Konica Minolta CM-25cG is a precise, handheld spectrophotometer designed to measure color and gloss simultaneously. Featuring a 45°c:0° illumination/viewing system and an integrated 60° gloss sensor, it is ideal for evaluating the color and gloss of automotive interior materials, high visibility textiles, and more.

Spectrophotometer CM-25cG

The Konica Minolta Spectrophotometer CM-25c is a compact yet powerful color measurement instrument with various features that ensure precision and convenience.

This spectrophotometer uses a 45°c:0° illumination/viewing system that offers color measurements that correlate with visual perception. In addition, it also comes with an integrated 60° gloss sensor, offering simultaneous color and gloss measurement. The spectrophotometer CM-25cG offers two measurement aperture sizes, 8mm (MAV) and 3mm (SAV), providing flexibility based on your measurement needs.

Featuring a symmetrical and compact design, the spectrophotometer CM-25cG enables easy measurement of hard-to-reach areas within the vehicle interior. Furthermore, it is equipped with a true optical sample viewer that facilitates easy sample positioning.

With a high inter-instrument agreement (IIA) with ∆E*ab < 0.15 and high repeatability of σ∆E*ab < 0.04, the CM-25cG enables effective digital color communication across the supply chain. It also comes with the user-friendly Configuration Tool CM-CT1 software that allows instrument settings to be created, written, and shared among multiple units. Through the optional Spectramagic NX/Spectramagic NX 2 Software, the user can set up measurement procedure with an explanatory image on the CM-25cG to enhance inspection workflow.
