Moisture and Density Analyzer


The MD-500 is a capacitance-based laboratory equipment that analyzes the moisture and density. It supports cherry, parchment, green beans and roasted beans measurement.
Its compact form allows you to carry it everywhere you need to measure the moisture and density. The results are automatically stored in the MD-500 internal memory and can be easily re-checked on display or laod the database into your computer.


The density analyzer 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.
