Overview
The EMSBC-231 Spectrophotometer is a precision color measurement instrument featuring 45/0 optical geometry (45° ring-shaped illumination and vertical viewing). It enables high-accuracy, non-contact color measurement between the probe and the sample, making it ideal for testing liquids, sauces, powders, and other sensitive materials. This instrument is independently developed and protected by independent intellectual property rights.
The EMSBC-231 Non-Contact Benchtop Spectrophotometer is designed for accurate color analysis and transmission in laboratories and R&D environments. It is also suitable for quality control and color measurement on automated production lines. Its applications cover a wide range of industries, including cosmetics, food (fruits, vegetables, sauces), plastics, electronics, paints, inks, printing, and ceramics. The instrument also supports fluorescent sample measurement.
With its innovative non-contact design, the EMSBC-231 allows direct color measurement from production lines while maintaining stable, repeatable, and high-precision results.
The EMSBC-231 ensures that no physical contact occurs during measurement, which helps prevent sample damage and eliminate the risk of cross-contamination.
