| Density can be determined quickly and with reasonable accuracy by floating a calibrated hydrometer in the juice. |
| With this method, the hydrometer does not float freely in the test liquid, but instead is attached to a suspension system affixed to a balance. |
| The surface level of the water will mark the specific gravity level and the potential alcohol level, both labeled on the hydrometer. |
| This is a hydrometer which is based on the principle that dissolved substances will cause a body to float. |
| The other piece of equipment is a device called a hydrometer, which measures alcoholic strength. |
| With this method, the hydrometer is incorporated into a precision lifting mechanism for easy and exact positioning in the test liquid. |
