R2 Refractometer - English

A 32% bigger, more detailed colour display.
R2 extract's bigger, higher resolution, colour display allows for a greater density of information, for more testing modes and greater versatility.

What are you in the MODE for?
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 is an average.

Stable test: Testing begins automatically when temperature change is detected. Final results display when a stable temperature is reached.

A modern upgrade to an old technology

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

Caps off! 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 achieved by a compensation between two separarely placed 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 running water and wipe dry. Couldn't be easier.
