Certified Alcohol Hydrometers
Â
Our Certified Alcohol Hydrometers are three point certified to IRS standards for proof, tolerances, and NIST traceability. These hydrometers are commonly used in distilleries that require certification.
Each hydrometer is 12 inches in length and comes with a laminated NIST-traceable certificate of calibration and a protective PVC case.
The certification is ordered with the hydrometer and requires 20-25Â business days for delivery.Â
VEE GEE Hydrometers are manufactured to exacting standards. Each hydrometer is individually tested and inspected to ensure the highest level of dependability.                                                         Â
