Feature Introduction
Simultaneous color and gloss measurement — perceive the complete texture of your product
Visual perception is a combination of color and gloss. Traditional methods require two separate instruments and two measurements, which are time-consuming and inefficient. We have innovatively integrated high-precision color difference measurement and gloss analysis into one device. With a single click, the screen instantly displays both color parameters (Lab, LCh) and gloss values (GU), enabling more comprehensive and efficient quality control.

Exceptional inter-instrument consistency — ensure global color communication
For enterprises with multiple production lines or extensive supply chains, consistency between instruments is crucial. Through advanced manufacturing processes and individual device calibration, we have minimized inter-instrument variation to within an extremely small range (ΔE*ab ≤ 0.2). This guarantees uniform color standards from laboratory formulation to production and customer inspection.

10-million-measurement lifespan — built for exceptional durability
The core light source is the “heart” of the instrument. The DC-27CG adopts a full-spectrum balanced LED light source, ensuring both stability and accuracy while achieving an unprecedented service life of 10 million measurements. This translates to longer equipment life cycles and lower ownership costs — a smart investment for the future.

Full-spectrum analysis from 360–740nm — no color detail overlooked
A wider wavelength range means more comprehensive color information. The DC-27CG covers the full visible spectrum from 360nm to 740nm and includes independent UV light source control. Whether measuring ordinary colors or special materials containing fluorescent or whitening agents (such as textiles, plastics, or paints), it precisely captures true color and eliminates metamerism.

Superior sample adaptability — confidently handle any challenge
Your measurement needs are already anticipated. With optimized optical structure and comprehensive accessory support, the DC-27CG easily measures samples from multiple industries including plastics, coatings, textiles, printing, food, and pharmaceuticals. Whether solids, powders, liquids, or pastes, you’ll always find the ideal measurement solution — truly achieving one instrument for multiple applications.

International-level precision — powered by CHNSpec’s confident core technology
Still hesitating between domestic and imported instruments? We’ve resolved that dilemma. The DC-27CG undergoes rigorous benchmark testing to ensure every color metric meets industry-leading standards. You’ll enjoy equal precision and stability as imported brands — at a more competitive cost.
