What it does
A precision digital refractometer designed for accurate Brix measurement in coffee cherries, enabling producers, researchers, and roasters to evaluate ripeness, sugar content, and harvest quality with scientific consistency. Built on the same optical and processing technology used in the R2 Extract line, the R2 PU provides fast, repeatable readings of soluble sugar concentration, helping users identify optimal picking windows, track fermentation progress, and improve post-harvest control. Its temperature-compensated design delivers stable results in farm, mill, and lab environments. Ideal for specialty coffee growers seeking reliable Brix data to support selective harvesting, fermentation profiling, and quality scoring. Supports modern quality-control workflows across the full coffee supply chain.
