NIST certified traceable hydrometer (alcoholometer)

Postby Zymurgy Bob » Fri Jul 10, 2015 1:19 pm

My friend who is going legit asked me who supplies the federally-certified alcoholometers. Do I remember that it's usually a 3-instrument set?

I know it's been mentioned here before, but can anyone tell me where to get these?

We got our at novatech. The hydros are (relatively) cheap, the certs are not.

Pint and Sugar. Either Google got smarter of I did, because I'm finding them now. but holy shit! Separate certification is truly spendy.

While I'm used to calibration of (electronic) instruments, and these all appear to be calibrated, and come with a a document attesting to that, so what is the "certification", what does it buy me, and why is it so damnably expensive?

From http://www.ttb.gov/foia/gauging_manual_toc.shtml

30.24 Specific gravity hydrometers.

(a) The specific gravity hydrometers furnished by proprietors to appropriate TTB officers shall conform to the standard specifications of the American Society for Testing and Materials (ASTM) for such instruments. Such specific gravity hydrometers shall be of a precision grade, standardization temperature 60 °/60 °F., and provided in the following ranges and subdivisions:

------------------------------------------------------------------------
Range Subdivision
------------------------------------------------------------------------
1.0000 to 1.0500...........................................0.0005
1.0500 to 1.1000...........................................0.0005
1.1000 to 1.1500...........................................0.0005
1.1500 to 1.2000...........................................0.0005
1.2000 to 1.2500...........................................0.0005
------------------------------------------------------------------------
No instrument shall be in error by more than 0.0005 specific gravity.

(b) A certificate of accuracy prepared by the instrument manufacturer for the instrument shall be furnished to the appropriate TTB officer.

And the assumption is?... that the TTB officer in question is actually conversant with scientific technical terms, trained to understand the certificate and it's import. Riiight! :roll:

Slainte!

The knowledge/understanding of the TTB officer has absolutely nothing to do with it. It's all about accurate measurements upon which tax due is based. 99% of laws governing liquor in the US are based on collecting tax. Besides, if this wasn't required you know that folks would use the shittiest, cheapest hydro possible.
