    CM-25d

    CM-25d Portable Spectrophotometer

    • CM-25d Portable Spectrophotometer

      The Konica Minolta CM-25d is a next-generation portable sphere spectrophotometer designed for measuring the color of flat or large samples in narrow spaces. It offers superior accuracy and inter-instrument agreement, making it ideal for color communication throughout the supply chain. The instrument is ergonomically designed for easy operation by right or left-handed users and is equipped with an illuminated viewfinder for accurate positioning.

      The Konica Minolta CM-25d Portable Sphere Spectrophotometer is an ideal instrument for color measurement in narrow spaces. With its precision, accuracy, ergonomic design, and additional features, it sets a new standard for easy and fast data handling, improving workflow, eliminating waste/rework, and offering customers general cost savings on color-related processes.

      Accuracy
      Precision and Accuracy

      The CM-25d offers superior accuracy and inter-instrument agreement with an IIA of 0.2 DE* (average of 12 BCRA tiles). This precision enables superior color communication throughout the supply chain from supplier to final assembly.

      Measurement Area and Design

      The instrument has an Ø8mm measurement area and is designed to minimize subject damage, providing repeatable results. The instrument surfaces that come in contact with the measurement subject are comfortable for both right-handed and left-handed users.

      Aperture Size
      Ergonomic Design and Features

      The CM-25d is lightweight and ergonomically designed for field applications. It features an optional Bluetooth™ and high-resolution TFT color display for easy data handling. The instrument offers filtering of stored data based on additional information (tagging) and image-based workflows for easy and simple usage by operators with limited instrument experience.

      Job Function

      The new Job function allows for graphical representation/instructions for routine color measurements to be made within specific processes. This feature, combined with a reduced measurement time, allows users of all levels to maintain high levels of productivity, accuracy, and consistency.

      WaveLength
      CT1
      CM-CT1 Configuration Tool

      The CM-25d comes with the CM-CT1 Configuration Tool software, which allows users to create and write instrument settings and compile them into a file to share within its supply chain to ensure consistent instrument settings.

      Konica Minolta Model Comparision

      The CM-26dG Series from Konica Minolta offers three variations of advanced portable spectrophotometers. The high-end CM-26dG and CM-26d models bring the industry's highest level of accuracy, with the CM-26dG capable of simultaneously measuring color and gloss, and the CM-26d specifically for measuring color. The lineup is rounded out with the high cost-performance model, the CM-25d.

      The main distinctions between CM-26d and CM-25d are that the 26d offers a replaceable target mask (which permits reading SAV at 3mm), incorporates UV, and has better accuracy and reproducibility (although only slightly). The software enables you to configure and synchronize multiple units across various locations or plants.
