DiFluid R2 Coffee TDS Refractometer

Master Extraction Precision with the DiFluid Coffee TDS Refractometer

For the modern barista and roasting professional, consistency is the ultimate goal. The DiFluid Coffee TDS Refractometer is a high-precision digital instrument designed to eliminate the guesswork from your brewing process. By measuring the Total Dissolved Solids (TDS) in your coffee, this device allows you to quantify extraction levels with laboratory-grade accuracy, ensuring that every cup—whether a delicate pour-over or a concentrated espresso—meets your exact flavor profile. Within seconds, you can transition from subjective tasting to objective, data-driven brewing, making it an indispensable tool for the premium coffee sector in India and beyond.

Advanced Optical Technology and Rapid Analysis

At the core of the DiFluid refractometer is a high-resolution linear image sensor paired with a professional-grade sapphire prism. This combination allows for a stunning ±0.02% accuracy in TDS measurement. Unlike traditional analog refractometers, the DiFluid utilizes an automated temperature compensation (ATC) algorithm, which adjusts for the sample's heat in real-time. This means you can test your coffee immediately after brewing without waiting for it to reach room temperature, significantly speeding up the calibration process in a fast-paced café environment or a home testing lab.

Seamless Integration with the DiFluid Café App

The DiFluid experience extends beyond the hardware through its integrated Bluetooth connectivity. By syncing the device with the DiFluid Café App, users can automatically record measurements, track extraction yield, and visualize brewing charts. This digital ecosystem allows you to save "Golden Cup" recipes and compare different batches over time. For professional roasters and quality control managers, this data logging is essential for maintaining brand consistency across multiple locations and identifying subtle shifts in bean performance or grinder calibration.

Robust, Pocket-Sized Engineering

Despite its sophisticated internal optics, the DiFluid Refractometer is built for the rigors of a working brew bar. It features an IP67 waterproof rating, allowing the sample well to be rinsed directly under a tap without risk to the electronics. The device is compact enough to fit in a pocket, yet powerful enough to provide a clear, backlit digital readout under any lighting conditions. Its rechargeable lithium battery ensures long-term reliability, removing the need for constant battery replacements during intensive cupping sessions.
