Are you looking to buy DiFluid R2 Extract Refractometer in Australia?

An essential tool for roasters, cuppers, and baristas. The refractometer measures the concentration of dissolved solids in an extraction; an important parameter for assessing the quality of coffee, as it is closely related to the coffee's strength and flavour profile. The DiFluid R2 Extract offers a precise reading in seconds and has a micro calibration mechanism that enables advanced temperature compensation.

High precision. If you’re aiming for perfection, the R2 Extract comes close. Its CMOS sensor offers results with a .02% precision and .0% accuracy in seconds. This refractometer also has a micro calibration layer for temperature compensation. To further stabilise the readings, the sample dish is made with aluminium which has better temperature conductivity.

Plus it has an ultra-clear HD screen to remove the struggle of reading the results.
