HK-7 Color Analyzer (Description)

The HK-7 IS THE ONLY AVAILABLE OPERATIONAL LED SYSTEM FOR MEASURING WHITENESS OR COLOR

The HK-7 is comprised of a Transmitter, a White Light Source, and a Sensor to measure the reflected light. It is crucial that the height of the sugar, the moisture of the sugar, the ambient light and ambient dust must be controlled for a good measurement.

This is a Continuous, measurement of product color in the color space CIELab. The evaluation takes place in the visible light sector from 400 - 700 nm. The output of the measurement results, occurs in 4 current output channels: L*, a*, b* and dE*.

One of the major advantages of using the HK-7 is that it is not using a Xenon-light but LED Lights!. This controlled LED illumination is responsible for an improved stability of the measurement.
