Hydrometer Test Cylinder
Used to hold the sample for taking gravity or proof readings. Available in plastic or glass. NOTE: If proofing spirits, you MUST use glass; the plastic can't handle high octane.
Also called an alcoholmeter. This marvelous tool shows the proof of spirits. The presence of sugar will distort readings, so this is only for pure spirits and spirits blended with water (not juice or sugar, etc). Proof scale 0-200.
