The large aperture CR-410 with specially modified firmware and purpose designed sample holder is used to provide colour measurements of coffee at all stages of the production process using industry standard measurements.
The CR-410C handheld coffee colorimeter is specifically designed to measure the colour of whole green beans, roasted beans, and roasted coffee using industry standard measurements.
The CR-410C is a tristimulus colorimeter that measures colour using filters with a close match to the spectral sensitivity function of the human eye. Using this technology, operators can achieve traceable measurement data for colour and colour difference that correlates with human perception.
The device firmware contains the Speciality Coffee Association of Americas (SCAA) Speciality coffee index to quickly, simply and repeatably calculate the colour difference from a standard, roast level (light, medium, medium dark, dark) and pass/fail tolerances.
Utilising this cost effective and portable setup, the operator can accurately measure the colour of coffee in various forms: whole green beans, roasted beans, roasted and lyophilized (Freeze Dried).

This sample holder enables the instrument to be held in position during powder sample measurement. Powdery samples are placed in the cups that are held in a sliding tray with three cups. This holder is best suited for fine powders although granular materials can be used in it as well. Enables the quick, easy, and precise measurement of powder with a CR-410.
Item comes with three cups and is not recommended for liquids.
Item Order Code: B027057
Spare cups for B027057 and B027058
