A moisture meter for coffee beans serves as one of the most critical quality control tools in the specialty coffee industry. Operators use it to measure water content in green coffee, parchment, and roasted beans at every stage from farm intake to pre-shipment verification. Accurate moisture readings protect against mould, uneven roasting, and flavor degradation.
At Coffee Pro Direct, we offer the Moisture MAC II, a lab-grade moisture analyzer trusted by exporters, Q-Graders, dry mills, and roasteries in over 30 countries. It delivers results in 10 seconds without requiring recalibration.
We don’t just provide equipment, we empower coffee professionals to work smarter and more confidently at every stage of production. Our Moisture MAC II is a lab-grade moisture meter for coffee beans, engineered specifically for the coffee industry to deliver fast, consistent, and reliable readings that support your quality control goals.
For professional coffee operations, moisture measurement accuracy typically needs to fall within ±0.1%–0.3% to ensure reliable quality control decisions across sourcing, storage, and roasting workflows. Used by roasters, exporters, Q-Graders, and quality labs worldwide, the moisture meter for coffee beans reflects our commitment to professional-grade performance with field-ready durability, the kind of tool you rely on every day.
“We are the prime solution for coffee lab equipment. Our goal is simple: to help you achieve excellence with every batch.”
Why Moisture Testing Matters
Moisture content is a critical factor throughout the coffee supply chain, influencing everything from storage and transport to roasting and flavour development. Improper moisture levels can result in mould growth, bean degradation, uneven roasting, and diminished cup quality. The Specialty Coffee Association (SCA) recommends maintaining green coffee moisture between 10% and 12% to ensure optimal quality.
The Coffee Pro Moisture MAC II allows professionals to validate green coffee on arrival or before export, monitor storage and post-harvest processing, and maintain consistent cupping and grading standards in compliance with ICO green coffee trade requirements. Accurately measuring moisture, it helps protect the integrity of your inventory from farm to warehouse. For coffee professionals who prioritize quality, moisture testing is not optional; it is an essential, foundational practice.

About the Coffee Pro Moisture MAC II
Unlike conventional moisture testers, the MAC II is built around a fixed-volume approach, eliminating the need for an internal scale. This unique design virtually eliminates the need for recalibration, making the device exceptionally easy to use.
Fixed-volume moisture measurement systems reduce calibration variability compared to weight-based systems, improving repeatability and reducing operator-dependent errors in high-throughput environments.
Built for Specialty Coffee
The Coffee Pro Moisture MAC II comes pre-calibrated for green coffee, parchment (pergamino), and cocoa, so users can start testing immediately. It includes a USB connection that allows teams to transfer data easily to a PC for record-keeping and analysis. Its design eliminates the need for internal balance calibration, ensuring accurate performance with minimal maintenance.
The MAC II delivers results in just 10 seconds without any sample preparation faster than conventional meters and ideal for rapid decision-making in both lab and field environments.
We build the unit with rugged housing to withstand real-world lab and field conditions, while its compact, lightweight design makes it ideal for remote testing and on-site use. The intuitive interface requires minimal training, allowing any team member to operate it confidently and efficiently.
This instrument is not a generic tool; it serves as a specialized solution developed specifically for the unique demands of the specialty coffee industry.
| Feature | Fixed-Volume Meter (MAC II Type) | Traditional Weight-Based Meter |
|---|---|---|
| Calibration Requirement | Minimal | Frequent |
| Measurement Speed | Fast (≈10 sec) | Moderate |
| Accuracy Stability | High | Medium |
| Operator Dependency | Low | High |
| Best Use Case | Labs & field QC | Controlled lab environments |
Our Clients Use It For:
