Description

Spectrophotometer CM-3700A P

The Konica Minolta Spectrophotometer CM-3700A Plus sets a new standard in benchtop spectrophotometry with state-of-the-art technology that delivers precise and reliable color measurements. As the latest flagship model from Konica Minolta, it builds upon the legacy of its predecessor, the CM-3700A model, combining innovation with unmatched performance. The CM-3700A Plus is engineered to meet the highest demands and is ideal for research and development, quality control, and computer color matching applications with stringent requirements.

The CM-3700A Plus, with an inter-instrument agreement of ΔE*ab 0.08 or less, ensures consistent measurement across all units of the same model, allowing seamless color management throughout the supply chain, from suppliers to final product manufacturers. It also offers good repeatability, with improvements in black color measurement accuracy. Additionally, the CM-3700A Plus maintains close compatibility with its predecessor, minimizing discrepancies in measured values and ensuring a smooth and efficient transition for users.

Unlike its predecessor, the CM-3700A Plus can simultaneously measure SCI (Specular Component Included) and SCE (Specular Component Excluded), boasting a faster measurement speed and improving overall operational productivity.

The CM-3700A Plus offers enhanced usability with a camera viewfinder feature, enabling easy and precise sample positioning directly from your PC monitor. Users can also save images alongside measurement data, simplifying data management and boosting efficiency. Equipped with an environmental temperature/humidity and a sample thermometer, the CM-3700A Plus allows users to check and record ambient conditions and sample surface temperature alongside color measurements. It also features the Wavelength Analysis & Adjustment (WAA) function, a Konica Minolta’s innovative technology that diagnoses and corrects any wavelength shifts in the instrument during each calibration. Additional features include a measurement status panel, a spacious transmittance chamber, and built-in storage for accessories, making the CM-3700A Plus both practical and user-friendly.
