Sap Hydrometer. Works similar to a syrup hydrometer except is calibrated to pick up much lower sugar content. Divide the sugar content which reads from the hydrometer into 86 and that's how many gallons of sap you need to make one gallon of syrup. For example, a 1.75 reading on the hydrometer will need just over 49 gallons. That's why I was dumping last nights take which was at or below 1.25 (almost 70 gallons required). BTW, the hydrometer is calibrated to read sap at 38 degrees F.
