DiFluid R2 Extract Refractometer, Digital TDS Meter for Coffee Concentration Testing

A 32% BIGGER MORE DETAILED, COLOR DISPLAY
R2 Extract's bigger, higher resolution, color display allows for a greater density of information, for more testing modes and greater versatility.

STANDARD TEST:
Press the button, and watch the results appear. It's just that easy. 

MULTI-TEST:
Set a number of tests, and let R2 do the rest. The result in an average.

STABLE TEST:
Testing begins automatically when temperature change is detected. Final results display when stable temperature is reached.

MICROCALIBRATION:
A huge leap in accuracy & precision
The Micro-calibaration layer compensates for external disturbances and physical deformations such as temperature changes or undissolved particles, greatly improving accuracy and stability.

FASTER, EASIER AND MORE ACCURATE:
R2 Extract utilizes a carefully calibrated 2D CMOS imaging sensor, reducing risk of misalignment and fragility, while increasing data collection and eliminating the need for a cap.

REMOVING EXTERNAL INFLUENCE:
Dual temperature sensors allow for incredible precision by reducing interference from the outside environment. This is achieved by a compensation between two separately place temperature sensors within R2 Extract.

NANO-SCALE HYDROPHOBIC LAYER:
The Nano-Scale Hydrophobic Layer prevents liquid from sticking to the glass, minimizing the need to touch it and providing an extra layer of protection against scratches assuring long life.

WATERPROOF FOR EASY CLEANING:
R2 Extract is IP67 water resistant, allowing you to simply rinse the sample dish under water and wipe dry. Couldn't be easier

ENVIRONMENTAL COMMITMENT:
R2 Extract ships with a quality metal reusable coffee spoon to replace single use plastic pipettes. Not only does this prevent plastic waste, but also helps to distribute heat from coffee, resulting in better accuracy, R2 Extract ships in sustainable packaging, and the charging cable does not contain toxic materials.
