The Konica Minolta Spectrophotometer CM-26dG is a Close Tolerance (CT) grade color measurement instrument developed for digital color data management. With tight inter-instrument agreement (IIA) and high repeatability, it is ideal for evaluating the color and gloss of plastics, smartphones/tablets exterior, paint & coatings, parts within the automotive interior, etc.

Spectrophotometer CM-26dG

The Konica Minolta d:8° portable Spectrophotometer CM-26dG is a versatile color measurement instrument that measures color and gloss simultaneously. It’s perfect for assessing the color and gloss of automotive interior parts, plastics, smartphone/tablet exteriors, and more, and is ideal for various applications requiring precise color and gloss evaluation.

The CM-26dG is designed for effective Digital Color Data Management, offering high inter-instrument agreement (IIA) with ∆E*ab < 0.12 and high repeatability of σ∆E*ab < 0.02. This reduces the reliance on physical samples while ensuring consistent color and gloss data throughout the supply chain.

This highly versatile and reliable color measurement instrument features a symmetrical and compact design that simplifies measuring hard-to-reach surfaces/areas such as the interior of a vehicle. It can switch between Ø8mm and Ø3mm measurement areas and includes a viewfinder for precise positioning of samples and small parts.

The CM-26dG comes together with the user-friendly Configuration Tool CM-CT1 software, enabling users to effortlessly create, write, and share instrument settings across multiple units, even across different global locations. When paired with Spectramagic NX/Spectramagic NX 2 Software, the CM-26dG facilitates the creation of image-based workflows within the instrument for the seamless execution of routine tasks.
