PERFECT COFFEE EXTRACTION WITH EVERY BREW

The DiFluid R2 Refractometer is one of most effective tools to instantly elevate your pour-over or espresso coffee. The R2 takes out the guesswork in recreating your favourite flavour profiles by measuring coffee extradition yields in Total Dissolved Solids (TDS).

Once you achieve the perfect brew, use the R2 Refractometer to measure the TDS% and save it for your next batch! Reduce waste, improve your consistency, and gain a deeper understanding of coffee extraction with every test.

The DiFluid R2 is one of the latest models of refractometers, implementing modern upgrades for the best-possible accuracy and precision.

±0.02% accuracy
The DiFluid R2 Refractometer can measure TDS% with incredible precision.

Aluminum Sample Dish
The Aluminum Sample Dish spreads heat from samples quickly and evenly for more reliable temperature measurements.

Self-Calibration
Using reference material, the DiFluid R2 performs micro-calibrations on every new test, adjusting for tiny variations and ensuring every reading is accurate.

Sleek, Digital Interface
With the DiFluid R2's digital screen, you can easily read measurements and navigate through settings.

CMOS Sensor
Housing a CMOS Sensor to better handle misalignment, the DiFluid R2 is more sensitive, accurate, and faster than other refractometers with CCD sensors.

Water-Resistant
IP67-rated so you can test, rinse, and repeat without worry. Please only rinse the DiFluid R2 under running water; do not fully submerge it.

CoffeeOS "Brew Control Charts"
In the CoffeeOS App, "Brew Control Charts" let you tell the DiFluid R2 exactly which flavour profiles you prefer and save them for next time. You won't need months of barista training to get perfect, consistent extraction with every brew.
