Spectrophotometer CM-3700A Plus
Click to Enlarge Thumbnails
Expanding on the performance and reliability of its predecessor, the benchtop Spectrophotometer CM-3700A Plus is an advanced measurement instrument designed to precisely evaluate the color and appearance of opaque, transparent, translucent, and fluorescent samples. The CM-3700A Plus has achieved a high inter-instrument agreement of ΔE*ab 0.08 or less. This enables more precise color management of multiple units and locations in the supply chain. The CM-3700A Plus has a 50% reduction in measurement time, and simultaneous measurement of SCI/SCE streamlining the operational process giving you greater efficiency. The main body also has space to store accessories such as white calibration plate, zero calibration box, target mask, etc. When used with the optional SpectraMagic NX2 software the camera viewfinder feature allows you to view the sample directly on your computer screen to ensure precise positioning. This feature also allows images to be saved with corresponding measurement data for more accurate management of data. The optional Wavelength Analysis & Adjustment or WAA, a Konica Minolta Sensing innovation, compensates for slight shifts in measurement values due to external factors.
Its advanced capabilities and unwavering performance enable users to formulate and match color quality standards more efficiently, maintain consistency in each batch of material, and help communicate color seamlessly internally and throughout the supply chain. All this makes the CM-3700A Plus ideal for color analysis, formulation, and quality control inspections within laboratory and manufacturing environments. The benchtop Spectrophotometer CM-3700A Plus is compatible with SpectraMagic NX2 software to record measurements and provide a more comprehensive color analysis, as well as others software to formulate color recipes for various applications and share real-time measurement data.
