The first portable d:8° geometry instrument with an integrated ISO compliant 60° gloss sensor

The CM-26d and CM-26dG are the successors to the widely used CM-2600d spectrophotometer and an upgrade in every respect.

Portable sphere type spectrophotometers with horizontal alignment, designed for maximum performance when measuring the colour of flat or large samples. These close tolerance devices perform measurement both including (specular component included - SCI) and excluding (specular component excluded - SCE) surface conditions in one measurement sequence, significantly faster than the previous generation.

The CM-26dG features an integrated ISO compliant 60degree gloss sensor, offering significant improvement in efficiency to many organisations who previously controlled these key appearance values independently using separate instruments, processes and reporting tools.

The devices have a straightforward modern user interface that simplifies the process of measuring and interpreting colour data. The easy UI and inclusion of user-centric features like job mode ensure that users can operate the device more efficiently and with reduced user errors.

Features

2 measurement apertures: choice of either medium aperture measurement (8mm) or small aperture measurement (3mm), to adapt to small or patterned samples

Integrated ISO compliant 60° gloss sensor (CM-26dG): gloss measurement data is captured and stored with colour data, greatly reducing the measurement and analysis time where both appearance characteristics are reported

Large colour display: Simple user interface minimises the risk of operator errors and measurement data is displayed both numerically and graphically

Rechargeable battery: lithium-ion battery is charged via USB bus power and additional batteries can be charged with external charger (optional)

Sample observation port: illuminated sample positioning window allows the operator to accurately and repeatably position the measurement aperture

Configuration Software: compatible with the CM-CT1 software that allows an administrator to quickly configure multiple instruments, lock device settings and perform remote troubleshooting and training over screensharing software

Close tolerance by default: maximise the accuracy and certainty of digital colour data throughout the supply chain, confident that all measurement data is traceable
