Our measuring instruments work with an R-G-B sensor whose filter curves correspond to the human eye (3-range method). From the red, green and blue components we calculate the Lab* values from which we then determine the Roche value. In our software, both the Lab* values and the Roche values are stored.
For our 3.0 systems, we offer a color sensor that is integrated into the worktable. This allows a quick and clean determination of the yolk color.
For the measurement, the egg is cracked on the worktable. If necessary, the egg white height is then measured. Then the yolk is positioned over the sensor and the measurement is triggered on the PC. The device has a USB port and can be connected directly to the PC.
