A single tool that can be utilised to predict yield, quality, pest and disease pressure and stress resistance.

The refractometer is an indispensable tool for Nutrition Farming®. This simple, robust instrument can utilise just a couple of drops of sap or juice to provide valuable data for crop management. It measures brix levels (total dissolved solids) which give an indication of plant sugars, minerals and vitamin content. The link between high brix levels and inherent pest and disease resistance has been conclusively established. Good brix levels also ensure good taste, longer shelf-life and better yields.


The refractometer measures brix from 0 – 32°Bx.

Pocket-sized and lightweight.

Accurate to within 0.2%.

The refractometer comes in a high-density plastic case lined with contoured foam.
