The Spectrophotometer CM-26dG is a Close Tolerance (CT) grade instruments 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 parts within automotive interior and smartphones/tablets exterior.

Spectrophotometer CM-26dG

The new d:8° portable Spectrophotometer CM-26dG, capable of measuring color and gloss simultaneously, is ideal for measuring and evaluating the color and gloss of automotive interior parts and smartphones/tablets exterior.

Develop

ed for “Digital Color Data Management”, the CM-26dG, with tight inter-instrument agreement (IIA) of ∆E*ab < 0.12 and high repeatability of σ∆E*ab < 0.02, help reduce the need of physical samples while ensuring color and gloss data measured and communicated remain consistent within a supply chain.

The symmetrical and compact design of CM-26dG makes it easy to measure hard-to-reach surfaces/areas such as the interior of a vehicle. Switchable between Ø8mm and Ø3mm measurement areas, the CM-26dG also comes with a viewfinder for accurate positioning on sample and even small parts.

The CM-26dG comes with quick and easy  Configuration Tool CM-CT1 software that allows user to create/write and share instrument settings amongst multiple units, even at various locations across the globe. When used with Spectramagic NX Software, CM-26dG allows user to create image-based workflows within the instrument for routine tasks.
