Vee Gee Scientific 6613-F IRS Alcohol Hydrometer — Proof Scale, 0–20 Proof Range, Size F

Product Description

The Vee Gee Scientific 6613-F is a borosilicate glass alcohol hydrometer calibrated to the U.S. Internal Revenue Service (IRS) proof scale, designed for measuring the alcohol content of very low-proof ethyl alcohol-based spirits and solutions. It features a 0 to 20% proof range, IRS Size F, 0.2% subdivision, and an approximate length of 305 mm (12 in). Global Test Supply It is ideally suited for distilleries, alcohol testing laboratories, and quality control environments working with very low-proof spirits, diluted alcohol solutions, or near-zero proof distillate cuts.

Meets IRS Specifications for Accuracy and Compliance Each hydrometer features a proof scale and is manufactured to meet strict IRS specifications for precision and consistency. Every unit is individually tested and inspected to ensure dependable results, making them ideal for distilleries, laboratories, and quality control environments. Veegee The proof scale and tolerances comply with Internal Revenue Service requirements, making this hydrometer appropriate for use in federally regulated distilled spirits production and testing. Calibrated for use at 15°C / 60°F — the standard reference temperature for alcohol proof measurement.

Individually Tested & Inspected Vee Gee hydrometers are manufactured to exacting standards, with each instrument individually tested and inspected to ensure the highest level of dependability, accuracy, and uniformity. This commitment to individual quality control gives laboratories and distillers full confidence in the precision of every reading.

Borosilicate Glass Construction The 6613-F is constructed from borosilicate glass for chemical resistance, thermal stability, and long service life. At 305 mm (12 in) in length, it is compatible with standard hydrometer jars and cylinders.
