Economy Tralle & Proof Hydrometer
Details
Hydrometer for testing alcohol levels in distilled spirits. Will only work in solutions of ethanol and water, will not read the alcohol levels of beer or wine.
Reads alcohol percentage on scale of 0-100%, and "Tralle's scale" (Proof) on a scale of 0-200. The economy version is functionally similar to the standard MT309 Proof and Traille hydrometer, but slightly lighter and at a lower cost.
