Simple, affordable, easy-to-use time proven device used for centuries to measure sugar and bio-nutrients in a variety of plant structures. A perfect way to document and verify the improved plant performance following BEAM additions to the soil biology and rhizosphere. Traditionally used by vintners to determine 'ripeness' and sugar content of grapes to gauge best time to harvest and brewers to help brew beer. It can now be applied to objectively measure the relative nutrient content of leafy greens, forage crops, tomatoes, fruits, carrots. A most useful tool whose time has come.
