Hydrometer Test Jar – Glass

This 100ml glass test jar provides a clear, stable vessel for checking specific gravity with a brewing hydrometer. Its slim shape keeps the sample volume modest while giving the hydrometer room to float freely.

How to use it

1. Draw a representative sample into the clean test jar.
2. Lower the hydrometer gently and spin it to dislodge bubbles.
3. Read at the liquid level, following your hydrometer’s instructions.

For accurate results, keep the jar level and avoid returning a tested sample to the fermenter.
