R2 Extract - Precise Measurement of Coffee Extraction for Perfect Flavor

Experience consistency in your brewing with R2 Extract, the dedicated refractometer from DiFluid. This advanced instrument is indispensable for baristas, coffee researchers, and coffee enthusiasts striving to optimize the taste and quality of their brews. This tool ensures uniformity, minimizes waste, and gives you deeper insight into the extraction process – so you can fine-tune your coffee to the precise flavor profile you love. R2 Extract is an essential part of the Brew Control System, helping you track, analyze, and perfect your brews.

R2 Extract measures the concentration of brewed coffee in TDS% (Total Dissolved Solids). Using refractive technology, it determines the concentration of dissolved substances in the liquid with high accuracy. TDS indicates the percentage of the coffee drink that comes from dissolved coffee material. TDS measurements are crucial for understanding the coffee's extraction level. By measuring caffeine concentration with R2 Extract, the CoffeeOS app can help you determine your extraction yield, so you can dial in your brew and produce exactly the flavor you want. R2 Extract provides high-accuracy TDS measurements so you can calculate extraction yield and understand how your coffee develops.

Why Choose R2 Extract?

✔ Dedicated to Coffee: Specifically designed for coffee measurements for maximum accuracy and user-friendliness.

✔ Reduces Waste and Increases Understanding: Get precise data that helps you optimize every brew and avoid mistakes.

✔ Fast and Easy: Only 4 seconds test time for instant results. High-resolution digital display presents results clearly and intuitively – perfect for both busy cafes and home use.

✔ Robust and Water-Resistant: IP67 protection makes cleaning simple – just rinse with water and wipe dry. Compact and lightweight design ensures long lifespan and easy transport.

✔ App Integration: Combine with CoffeeOS to plot your brews on control charts and explore your preferences. Track and compare each brew in CoffeeOS to maintain repeatable results – ideal for cafes, roasteries, or other coffee businesses seeking quality assurance.

✔ High Quality: Each unit is thoroughly inspected during production to ensure top quality from DiFluid. Fast calibration and adjustment ensure consistent measurements over time.

Data-Driven Brewing with CoffeeOS

Even without automatic brew recording, you can manually enter brew parameters in the CoffeeOS Brew Control Chart and match them with extraction data for effective fine-tuning. Use R2 Extract data in CoffeeOS to adjust grind size, ratios, and brewing techniques to achieve optimal flavor in every cup. Gain professional-level insights into your extraction trends via CoffeeOS, improving quality and efficiency over time – even without full automation.

Modern Sensor Technology

2D CMOS sensors handle misalignment well. Their larger, distributed photosensitive area reduces accuracy loss from minor shifts or handling while improving data collection. Dual temperature sensors and hydrophobic sensor protection further enhance precision.

Accuracy with Micro-Calibrations

Each test uses a reference material for precise micro-calibrations that adjust for small variations and ensure every reading is accurate. The aluminum-based sample bowl distributes heat evenly over the sample and maintains stable temperatures for more reliable measurements.

Easy Cleaning with IP67 Water Resistance

Just rinse with tap water and dry.* Easy cleaning and reset/calibration keep the device ready for the next use.

*Avoid full immersion. You can do it, but then the port gets wet, and you can't charge until it is dry. Just rinse the bowl.

We care about the details

At DiFluid, we take manufacturing attention to detail very seriously – every single part is inspected as it comes off the assembly line to ensure maximum quality.

Plot your brew on one of the brew control charts to better understand your preferences and bring out the flavor profiles you desire.

How to Use R2 Extract – Step by Step

1. Prepare the sample: Take a small amount of your brewed coffee (approx. 0.3 ml).
2. Apply to the bowl: Drip or pipette the sample onto the heated aluminum bowl – it distributes heat evenly.
3. Measure: Press the button for a quick 4-second scan. The app calibrates automatically.
4. Analyze: View TDS% in the CoffeeOS app and adjust your recipe based on the results. Manually enter your brew parameters to plot on the Brew Control Chart.
5. Clean: Rinse the bowl with water and dry it for the next use. Tip: Start with a reference coffee to calibrate your taste palette – experiment with TDS between 1.2-1.5% for optimal balance.
