The MD-500 moisture and density analyser can deliver readings from coffee cherries, parchment, green beans, and roasted beans. With easy-to-use functionality, a simple switch enables you to change between the modes depending on what you are measuring. The MD-500 has unique weight calibration to obtain accurate density readings that are measured within 0.5%. The last 100 analysis results are automatically stored on the MD-500's internal memory for quick referencing. These results can also be downloaded directly to your computer via the included USB cable.
The density analyser reflects the hardness of coffee beans. From a roaster's perspective, knowing the moisture content of beans and cherries is a key component in providing critical information surrounding the shrinkage percentage of beans before they are roasted. It also helps determine the storage environment of the beans by checking the moisture level of roasted and green beans, which affects cupping quality.
