Spectrophotometer CM-25cG
CM-25cG is a 2-in-1 portable spectrophotometer built with with 45°c:0° geometry and an integrated 60° gloss measurements
The Konica Minolta Spectrophotometer CM-25cG is a handheld color measurement device that is designed to accurately measure and analyze the color and appearance of various materials and products. It is commonly used in industries such as printing, paint manufacturing, plastics, textiles, and cosmetics, among others.
The CM-25cG uses a spectral measurement method that analyzes the spectral reflectance of the sample being measured. This allows for highly accurate color measurements, as it takes into account the full spectrum of visible light, rather than relying on a limited number of color patches or samples.
The device is capable of measuring a variety of color metrics, including CIE Lab*, CIE LCh, Hunter Lab, and XYZ, among others. It also has a built-in gloss meter for measuring gloss and specular reflection.
The CM-25cG features a user-friendly interface and can be easily connected to a computer for data analysis and reporting. It is lightweight and portable, making it ideal for on-site color measurement and quality control.
The CM-25cG spectrophotometer is not only the successor to CM-2500d but is designed and built to measure both color and gloss simultaneously. CM-25cG greatly improves work efficiency by eliminating the need to switch between two instruments (one for color and one for gloss) for each measurement thus reducing the takt time and providing color and gloss data from exactly the same measurement spot for more accurate quality control.
The CM-25cG is built with a changeable apertures of 8mm (MAV) and 3mm (SAV) circumferential illuminant system and a measuring time of approximately 1 second. CM-25cG provide fast accurate and stable measurement even on curve surfaces.
The CM-25cG with symmetrical and compact design allows easy measurement where hard to reach areas within the vehicle interior. TheCM-25cG come with a built-in optical finder for perfect sample positioning and is the 1st instrument to offers such features in a 45°c:0° geometry spectrophotometer. The CM-25cG spectrophotometer is build with high Inter-Instrument Agreement (IIA) and high Inter-Model Agreement (IMA) ensure perfect measurement data correlation between instruments.
Overall, the Konica Minolta Spectrophotometer CM-25cG is a powerful and versatile color measurement device that can help businesses ensure consistent and accurate color reproduction in their products.
