Description
A coffee moisture meter that ends guesswork at intake
A batch of green beans reading 11% on one gauge and 13% on another isn’t a rounding error — it’s a roast plan built on guesswork. The DiFluid CoffMeter M1 gives Indian roasters, importers, and cupping labs a portable coffee moisture meter that settles the question in under two seconds.
Two readings, one 2-second test
Moisture and density are measured together on every scan, so you get a complete quality profile of a lot without running samples twice. The patented Bean Sweeper standardises sample placement, removing the operator variance that skews manual moisture checks.
Built for the counter and the lab
- ±0.2% moisture accuracy — tight enough for export-grade quality control
- ±1 g/L density accuracy for consistent roast profiling
- Reads green beans, roasted beans, parchment coffee, and dried cherries
- 500-entry data logging for batch-to-batch traceability
- 10-hour battery for a full day on the cupping table or intake counter
Precision instrumentation, field-ready design
Dual moisture + density
Complete analysis in ≤2 seconds, with ±0.2% moisture precision and ±1 g/L density precision in a single scan.
Wide sample support
Tests green beans, roasted beans, parchment coffee, and dried cherries — one meter across the whole supply chain.
2.31" touchscreen
HD display with an intuitive interface and on-device logging for up to 500 entries.
Patented Bean Sweeper
Standardises sample prep so results stay repeatable regardless of who’s operating the unit.
Field-ready build
445 g, 10-hour battery life, and a protective carry case for intake stations, warehouses, or roastery floors.
Smart calibration
Ships with a standard calibration sample so every unit reads true out of the box.

Frequently asked questions
How accurate is this coffee moisture meter compared to lab ovens?
The CoffMeter M1 delivers ±0.2% moisture accuracy and ±1 g/L density accuracy, comparable to standard lab reference methods but with results in under 2 seconds instead of hours.
Can it test roasted beans and parchment, not just green coffee?
Yes. It reads green beans, roasted beans, parchment coffee, and dried cherries, covering intake through post-roast quality checks.
How long does the battery last on a full charge?
The 2500mAh battery runs for 10 hours of continuous use and recharges fully via USB-C in about 4 hours.
Does it need regular calibration?
A standard calibration sample is included so the unit can be checked and recalibrated for reliable, repeatable results over time.
How many readings can it store?
The touchscreen interface logs up to 500 entries directly on the device, useful for tracking batches without a separate logbook.
For anyone who can’t afford a bad moisture reading
Roasters tracking batch consistency, green coffee buyers verifying quality at intake, cupping labs and Q-graders, and home roasters who want professional-grade data will find the CoffMeter M1 fits into daily workflow without slowing it down.
