0-100 alchol Hydrometer and 250ml cylinder

This 0 to 100% alcohol hydrometer comes with a 250ml measuring cylinder. An alcohol hydrometer (also called an alcoholmeter) with a 250ml cylinder is the standard setup for measuring the alcohol by volume (ABV) of distilled spirits.

Alcohol Hydrometer (0 to 100% ABV)

• Purpose: For distilled spirits only (such as vodka or gin). It measures the ratio of ethanol to water.
• Range: 0% to 100% alcohol by volume (ABV), often with a proof scale (0 to 200 proof).
• Calibration: Most are calibrated to read accurately at 20°C.
• Limitation: It can't be used for beer, wine or liqueurs. The sugar and solids in those drinks increase the density, so the meter won't sink properly and gives a wrong reading.

250ml Measuring Cylinder

• Why 250ml? An alcoholmeter is longer than a standard beer or wine hydrometer. A 100ml cylinder is often too short, so the meter touches the bottom before it can float freely.
• Glass or plastic:
  • Glass: Clearer, making it easier to see the meniscus (the curve of the liquid) for precise readings.
  • Plastic (polypropylene): Durable and very hard to break if dropped, which suits busy or outdoor settings.

How to Take a Reading

1. Fill the cylinder: Pour the spirit into the 250ml cylinder until it's about 80% full.
2. Insert the meter: Gently lower the hydrometer into the liquid. Don't drop it, as hydrometers are fragile.
3. Spin to release bubbles: Give the hydrometer a slight twirl to release air bubbles that could make it float too high.
4. Read at eye level: Once it settles, read the scale where the bottom of the curved liquid surface (meniscus) meets the glass.
