Description

The Konica Minolta Spectrophotometer CM-25cG delivers a specialized, high-precision solution for the simultaneous evaluation of color and gloss in professional manufacturing environments. Quality assurance teams and laboratory technicians utilize this two-in-one instrument to validate the appearance of automotive interiors, high-visibility clothing, and complex plastics with absolute accuracy. This specific model addresses the unique requirement of correlating digital measurements with human visual perception through its 45°c:0° circumferential illumination. Consequently, your facility gains a significant technical advantage by eliminating the need for two separate instruments during critical inspection cycles.

Instead of managing multiple devices that may introduce measurement drift, your team achieves a streamlined analytical workflow with the Konica Minolta CM-25cG. The system provides a high-performance 60° gloss sensor integrated directly alongside the spectrophotometer optics. Therefore, you can confidently capture color and gloss data at the exact same point on a sample surface while maintaining a high inter-instrument agreement of ΔE*ab 0.15.

Konica Minolta CM-25cG Technical Advantages

This portable spectrophotometer packs advanced features for demanding automotive and safety equipment production. It features a true optical sample viewer that allows technicians to see the target area directly through the high-resolution display. This visual feedback ensures that your engineering team captures exact data from specific textures or small structures without the risk of misalignment. Furthermore, the unit delivers a switchable aperture system that supports both MAV (Ø8mm) and SAV (Ø3mm) measurement areas to accommodate varying sample sizes.

The CM-25cG also features an ergonomic vertical design that simplifies measurement on curved parts and recessed areas within vehicle cabins. Technicians can operate the instrument comfortably with one hand while monitoring real-time spectral graphs and PASS/FAIL judgments on the back-lit LCD screen. Additionally, the unit supports the latest SpectraMagic™ NX2 software for comprehensive data management and reporting across the global supply chain.

Modern Supply Chain Integration

Modern facilities require robust connectivity and high-speed data management for industrial scaling. Therefore, the CM-25cG series includes standard Bluetooth® and USB interfaces for effortless data transfer to external software platforms. It supports the Konica Minolta Configuration Tool CM-CT1, allowing for straightforward secondary development and shared instrument settings between multiple factory sites. The durable housing and long-lasting lithium-ion battery ensure the instrument remains the essential tool for color audits on the factory floor or in the field.

When your project demands the highest level of appearance precision and combined sensor technology, the Konica Minolta CM-25cG stands out as the premier choice. Stop settling for low-speed tools that hide critical gloss deviations in your production prototypes.
