Probat introduces Colorette 4 colour measuring unit

Probat-Werke, one of the world`s leading manufacturer of plants and machinery for the coffee industry, launches a new measurement device for precisely determining the colour of ground roasted coffee.

The most recent addition to the Probat-family of quality control equipment, the Colorette 4, is specifically designed to accurately monitor the degree of roast. This portable and extremely precise control device works according to the principle of reflection measurement, unaffected by ambient light. Its extended functionality, capacitive touch-screen as well as quick and easy calibration allow for highly user-friendly operation.

By means of a stripping device, the coffee sample is prepared and placed at the measuring point of the Colorette 4. It then is illuminated by a clock-pulsed, shining white LED. A sensor captures the reflected light for colour value determination. The result can then be displayed in multiple scales if required. For further processing of the measured values, an Ethernet-port allows for the connection to a local computer or optionally the integration into the Probat Pilot Plant system. A USB interface enables users to save any measuring results on an external storage device. The indication in different scales such as the Colorette colour scale, a device-independent, standardized L*a*b colour scale and a user defined colour scale makes it possible to use this unit flexibly and to adapt it to individual requirements.

By using monochromatic light the comparability of colour values of different measuring devices is greatly enhanced. The ageing behavior of the sensor and the LED is also vastly improved. The Colorette 4 is extremely low-wear and guarantees most exact and reproducible measuring results during its entire lifetime.

“The Colorette 4 delivers extremely precise and reproducible measuring results for safe and simple colour identification of ground roasted coffee samples. Its enhanced functionality and flexibility make the Colorette 4 an indispensable tool for monitoring coffee quality,” said Andreas Rinke, manager/portfolio management at Probat, Emmerich am Rhein, Germany.
