Sugar Refractometer

Products Description Use this item to gauge the health of your plants by measuring their sugar content. This method is used by horticulturists to indicate plant stress before the plant shows symptoms. Simple to use: Just extract one drop of liquid (sap) from the leaf stem onto the glass plate, then turn toward the sun. Range 0-32% brix, resolution 0.1%. A high brix indicates adequate nutrition and is an indicator of fertilization success. Plants with high brix (reading above 12) sugar content also have good "immune systems."
