Moisture content is one of the fundamental parameters used when evaluating green coffee and can be monitored during purchasing, receiving, storage and before roasting.

CoffMeter M1 offers a 1–50% moisture range, 0.1% resolution and ±0.2% accuracy.

Fast measurement makes it practical to test multiple samples or coffee lots without slowing down the daily quality-control workflow.

Bulk Density describes how much coffee mass is contained within a given sample volume.

Density can provide useful information when comparing origins, varieties, processing methods and lots, giving roasters another physical parameter to consider during roast development.

CoffMeter M1 provides a 0–1200 g/L density range, 1 g/L resolution and ±1 g/L accuracy.

One of the key advantages of CoffMeter M1 is its speed.

The instrument can measure Moisture and Density in ?2 seconds, making it practical for everyday use in a warehouse, quality laboratory or roasting environment.

CoffMeter M1 supports several sample types and is not limited to green coffee beans.

• Green Coffee Beans
• Roasted Coffee Beans
• Parchment Coffee
• Dried Coffee Cherries

This makes the instrument useful at different stages of the coffee supply chain, from production and trading to roasting and quality control.

A typical green coffee measurement requires approximately 150 g of sample, depending on the density of the coffee.

Consistent sample preparation is important when results need to be compared between different testing sessions.

The integrated 2500 mAh lithium battery provides up to 10 hours of continuous operation.

A full charge takes approximately 4 hours via USB-C, making the instrument practical for use in laboratories, warehouses and sample evaluation environments.

Correct calibration is essential when building a repeatable quality-control workflow.

CoffMeter M1 is designed so that calibration can be performed by the user, making routine maintenance of measurement consistency more convenient.

CoffMeter M1 is designed for Bluetooth connection with the CoffeeOS ecosystem, allowing Moisture and Density measurements to become part of a structured digital coffee workflow.

DiFluid currently lists CoffeeOS connectivity for M1 as an upcoming feature.

Firmware update capability allows the instrument to receive improvements and new functionality as the DiFluid ecosystem continues to develop.

CoffMeter M1 focuses on the two core measurements of Moisture and Bulk Density, providing a fast and practical solution for everyday coffee quality control.

DiFluid Omix adds additional measurements including Water Activity, True Density, Screen Size, Bean Volume and further physical coffee data.

For professionals primarily looking for fast and repeatable moisture and density testing, CoffMeter M1 provides a highly practical solution.
