Hydrometer Test Jar 240 ml - 8 oz. (12 in | 30 cm)

Tall Testing Jar for Hydrometer Readings, Fermentation Tracking and Beverage Testing

The Hydrometer Test Jar is an essential tool for brewers, winemakers, cider makers, and fermentation hobbyists who need reliable hydrometer readings. With a 240 ml / 8 oz capacity and a 12 in / 30 cm height, this tall, narrow jar allows proper hydrometer submersion while using only a small sample of liquid.

Made in Canada, this clear test jar provides excellent visibility for reading hydrometer scales, helping you track specific gravity, potential alcohol, sugar levels, and fermentation progress with confidence. Using a dedicated test jar also helps avoid placing your hydrometer directly into the fermenter or bottle, reducing contamination risk.

How to Use

1. Clean Before Use: Wash the test jar before taking a sample.
2. Sanitize if Needed: Sanitize before use if the sample may be returned to the batch.
3. Fill with Sample: Add enough liquid to allow the hydrometer to float freely.
4. Insert Hydrometer: Gently lower the hydrometer into the test jar.
5. Read the Scale: Take the reading at the liquid surface according to your hydrometer instructions.
6. Record Results: Track specific gravity, potential alcohol, or fermentation progress as needed.
7. Clean After Use: Wash with warm, soapy water, rinse, and dry before storing.

Frequently Asked Questions

• Q: What is a Hydrometer Test Jar used for?
  A: It is used to hold a small liquid sample so a hydrometer can measure specific gravity, potential alcohol, sugar levels, or fermentation progress.
• Q: What size is this test jar?
  A: This test jar has a 240 ml / 8 oz capacity and measures 12 in / 30 cm tall.
• Q: Can I use it for beer and wine?
  A: Yes. It is suitable for beer, wine, cider, mead, kombucha, fruit wine, and other compatible beverage testing.
• Q: Does it include a hydrometer?
  A: No. The hydrometer is sold separately unless specifically included.
• Q: Why use a test jar instead of the fermenter?
  A: A test jar allows you to take readings from a separate sample, helping reduce contamination risk and making hydrometer readings easier.
• Q: Should I return the sample to the fermenter?
  A: For best practice, do not return tested liquid to the fermenter to avoid contamination.
• Q: Is it made in Canada?
  A: Yes. This Hydrometer Test Jar is made in Canada.
• Q: How should it be cleaned?
  A: Clean with warm, soapy water after each use, rinse thoroughly, and dry before storing.
