12" Sap Hydrometer 0-12 Degrees Brix Sap Hydrometer 12". 0-12 degrees Brix. Brix calibrated at 38 degrees F. Use to monitor your sap's sugar content. Great when buying sap. State of Vermont approved. Higher accuracy than the 7" sap hydrometer (divided into 1/10 degree increments). Jones's Rule of 86: Divide your sap sugar content into the number 86 to determine the gallons of sap needed to produce one gallon of syrup.
Please note: This hydrometer is not compatible with our hydrometer cups (it is designed to float in a larger gathering container, as it is too long for the standard cup and too wide for the smaller 1" cup), nor is it to be used in the boiling process, as it will not determine when sap has turned to syrup.
