whiskeytango Posted August 24, 2014 Share Posted August 24, 2014 Anyone out there using these new Alcohol meters? http://www.anton-paar.com/us-en/products/group/alcohol-meter/ Link to comment Share on other sites More sharing options...
Micah Nutt Posted August 24, 2014 Share Posted August 24, 2014 I liked our 6 month old $2400 DMA 35 until I dropped it in my lap while calibrating it and it fell 3' to the floor resulting in a broken horseshoe glass. Anton-Paar doesn't do repairs. How much is it? But more importantly is it any more durable than the DMA 35? Link to comment Share on other sites More sharing options...
MikeW Posted August 24, 2014 Share Posted August 24, 2014 Looks like the Snap 40 is accurate to .2% at $1200+/- and the Snap 50 to .1% at $3500+/-. Are these ok with the TTB? Can you check gravity of a fermenting mash with them as well as proof spirits? Link to comment Share on other sites More sharing options...
jeffw Posted August 25, 2014 Share Posted August 25, 2014 I would say those are not accurate enough for the TTB. That said, does anyone have a list of approved digital hydrometers for TTB tax reporting? I tried calling the TTB lab but never could get anyone to call me back. That Snap 50 might be good for quick measurement and just double checking your manual work with a hydrometer. Link to comment Share on other sites More sharing options...
jheising Posted August 25, 2014 Share Posted August 25, 2014 Here are the CFRs if you're interested: http://www.ttb.gov/foia/gauging_manual_toc.shtml#27:1.0.1.1.25.3.504.4, specifically: No instrument shall be in error by more than 0.0005 specific gravity My back of the napkin calculations show that to be about 0.065% ABV (please double check). So yeah, as jeffw says, they don't appear to be accurate enough. Link to comment Share on other sites More sharing options...
JohninWV Posted August 25, 2014 Share Posted August 25, 2014 We have both the DMA 35 and the DMA 5000M. The handheld is nice for quick reads, but I've seen it off more than 1 degree proof from the big machine. Link to comment Share on other sites More sharing options...
Jedd Haas Posted August 26, 2014 Share Posted August 26, 2014 Here is a link to the TTB PDF of approved devices. Link to comment Share on other sites More sharing options...
jeffw Posted August 26, 2014 Share Posted August 26, 2014 Thanks for the post Jedd. Anyone try out the one from Rudolph Research? I talked to them and they seemed nice and it is definitely more affordable than the DMA 5000. Link to comment Share on other sites More sharing options...
nabtastic Posted August 26, 2014 Share Posted August 26, 2014 The DMA 5000M suggested use requires their "alcolyzer" to be used with liqueurs and is the only AP approved for tax reporting. The Mettler-toledo is cheaper but requires a bench still (in place of the AP alcolyzer) to control for solubles, currently waiting on word from RR.. I have no experience with any of these and am currently researching which to purchase as well. Would love to hear feedback from any actual users. MT offers two options the DM 45 and DM 50 both of which are cheaper and accurate enough (1x10^-5). I'd like some reviews on bench stills as well, but thehttp://www.pelletlab.com/distillation_equipment was recommended by a user in another post and thats only a $240...which is about $14,000 cheaper than the alcolyzer.
