Description
Stop Eyeballing Roast Color
Every roaster knows the frustration of a batch that looks right but tastes off — visual judgment shifts with light, mood, and fatigue. The DiFluid CoffMeter A1 coffee color meter removes that variable, giving Indian roasters and café teams a number they can trust every single time.
Data Instead of Guesswork
Near-infrared sensing reads a single point across your sample and returns an average Agtron value on a 0–150 scale, with 0.1 resolution. No warmup, no calibration ritual before every use — just a 3-second reading and a number you can log, compare, and defend.
Built for Real Workflows
- ±0.5 Agtron accuracy across whole beans and grounds
- Dual-side sample plate with built-in overspill tray
- CoffeeOS app for wireless storage and roast tracking
- Pocket-sized metal body — no bench space required
Facts, Not Filler
Agtron Precision
Measurement range of 0–150 Agtron with ±0.5 accuracy and 0.1 resolution — tight enough to catch roast-to-roast drift before it reaches the cup.
Dual Sample Modes
Reads whole beans at 17–19g or grounds at 2–4g on the same one-piece plate, so green coffee, roasted beans, and ground samples all get consistent treatment.
CoffeeOS Integration
Every reading syncs wirelessly to the CoffeeOS app for logging, trend analysis, and batch comparison — turning a single-use meter into a running quality record.
3-Second Readings
No warmup cycle. Load the sample plate, press once, and get a stable result — fast enough to check every batch without slowing down the roast schedule.
All-Day Battery
A 1500mAh battery delivers roughly 8 hours of continuous use over USB-C, enough for a full day of quality checks between charges.
Genuinely Portable
At 74 × 74 × 70mm and 208g, the CoffMeter A1 fits in a roasting toolkit, apron pocket, or café drawer — built to travel between roastery and counter.
From Home Roaster to Café Counter
At home, this coffee color meter turns trial-and-error roasting into a repeatable process — dial in a profile once, then hit the same Agtron number every batch. On a café counter, it becomes a fast supplier-verification tool: check incoming roasted lots against your house standard before they hit the grinder.

Frequently Asked Questions
Does this coffee color meter work on both whole beans and ground coffee?
Yes. The dual-side sample plate is designed for whole beans at 17–19g on one side and grounds at 2–4g on the other, both read by the same near-infrared sensor.
How accurate is the Agtron reading?
The CoffMeter A1 reads across a 0–150 Agtron scale with ±0.5 accuracy and 0.1 resolution — precise enough to flag small batch-to-batch shifts.
Do I need to calibrate it before every session?
A calibration plate is included in the box for periodic calibration, but the unit requires no warmup before taking a reading — just power on and measure.
How is data stored and reviewed?
Readings sync wirelessly to the CoffeeOS app, where roasters can log results, track trends across batches, and compare roast profiles over time.
Is it practical for a busy café counter?
Yes. Readings take about 3 seconds, the body is compact metal at 208g, and the battery runs roughly 8 hours per charge — built for quick checks between service.
Built for Roasters Who Measure, Not Guess
The DiFluid CoffMeter A1 suits home roasters refining a profile, roasteries running quality control between batches, and café owners verifying that incoming roasted coffee matches spec — anyone who wants an Agtron number instead of an opinion.
