The Coffee Pro Moisture MAC II uses the electrical properties of water to provide an indirect method of moisture determination. Instead of using a balance to determine the mass of the sample, it has a fixed volume sample cup.
The screw-down compression cap is used to help provide uniform density. Because there is no internal balance, these units virtually never fall out of calibration. Made with quality components and rugged design to withstand operating conditions in the field and ensure years of trouble-free service.
