Product features

（1）Ultra-high repeatability accuracy: dE*ab ≤ 0.04

Repeatability accuracy is an important indicator to describe the accuracy of spectrophotometers. The is spectrophotometers are evaluated on the basis of a rigorous standard of repeatability, which is unmatched by any other spectrophotometer in its class.

（2）Excellent inter-stage consistency

The superior level of technology and craftsmanship ensures that this spectrophotometer has excellent inter-instrument agreement. The use of BCRA series standard colour bricks for colour transfer and colour value traceability an excellent level of inter-stage variation.

（3） Calibration base and zirconium reference with a Mohs hardness of 9 to calibrate the instrument, ensuring long-term stability

Compared to existing products, this spectrophotometer does not require frequent manual calibration when in use. Simply place it on the calibration base and the instrument will automatically calibrate the overall instrument function and accuracy according to its own state and environmental factors, ensuring that the instrument is always in a stable state and ready for use.

（4）Over 30 measurement parameters and nearly 40 evaluation light sources available

This spectrophotometer offer 30+ measurement indicators such as spectral reflectance, CIE-Lab, CIE-LCh, ΔE*ab, opacity, whiteness, yellowness, etc.; and nearly 40 evaluation light sources to choose from such as A, B, C, D50, D55, D65, etc., covering almost all colour measurement indicators and light source types in the industry.

（5）Use the powerful PC-based colour management system ColorExpert*

This spectrophotometer is supplied with a Windows colour management system, ColorExpert, which connects to This spectrophotometer via USB cable.

ColorExpert is a full-featured colour management software with four functional modules: My Colours, Colour Check, Colour Matching System and Personal Centre.
