Hydrometer Test Jar Glass
Checking the Specific Gravity of unfermented and fermented beverages with a Glass Test Jar is quick and easy. To test for gravity, use a Fermtech Wine Thief to remove a liquid sample from a fermentation vessel and fill the glass test jar with the sample. Place a hydrometer in the Glass Test Jar and note the location where the liquid crosses the stem of the hydrometer.
Easy to clean and sanitize, the Glass Test Jar will accommodate all of Brew and Grows Hydrometers and, unlike plastic versions, proves resistant to clouding over time.
