The North Mountain Supply premium glass proof and tralle hydrometer kit is designed for distillers and spirit makers who need reliable alcohol measurements in clear, distilled products. This alcoholmeter style hydrometer provides dual scales so you can read both proof and tralle values at a glance, making it easier to verify and document the strength of your spirits.
Measurement ranges:
-
Proof scale from 0 to 200
-
Tralle scale from 0 to 100
These ranges cover the typical alcohol levels for most distilled spirits, allowing you to check strength during blending, cutting and final proofing. The clearly marked dual scales make it simple to take readings in your preferred unit without conversion charts.
The hydrometer is made in France from quality glass and is:
-
Lead free
-
Mercury free
This construction avoids the use of heavy metals that were traditionally found in some older instruments and reflects a more modern, safety conscious design.
The kit includes:
-
One glass proof and tralle hydrometer
-
A clear test jar sized to accommodate the hydrometer and sample
-
A protective plastic storage case to help prevent breakage when not in use

Using the kit typically involves:
-
Filling the test jar with your clear distilled spirit to the recommended depth.
