Temperature of your syrup can drastically affect the buoyancy of your hydrometer. Traditionally, the only way to get an accurate hydrometer reading was to measure your syrup sample’s temperature and then use a compensation chart to calculate where the hydrometer should actually be floating. What a pain!
The Murphy Compensation Cup does all those calculations for you so you NEVER have to even think about it again. The dial on the Murphy Compensation Cup will indicate the actual location of 66.9ºBRIX on your hydrometer based on your syrup sample’s current temperature. If your syrup sample’s temperature changes, so will the reading on the Murphy dial, giving you the real-time feedback you need to take a quick and accurate measurement.
INSTRUCTIONS FOR CARE
Never submerge the face of your Murphy Dial in liquid nor expose it to excessive steam/moisture for extended periods of time. To safely clean the dial, simply wipe the face with a clean, damp cloth. Never turn or alter the screw on the back of the dial.
