Scale? 10 kg to 0.1 g

Postby NorthwoodsRockets » Tue Feb 16, 2016 1:23 pm

Looking for a good mixing scale. I would like to keep a total weight as I add components to my mixing bowl as a double check. Suggestions?
Dan, Did you get this scale? Did you like it? http://www.ebay.com/itm/10kg-5-6-3kg-x-0-1g-Big-Digital-Electronic-Food-Balance-Scale-LB-Lab-Weigh-457A-/271648284462?var=&hash=item3f3f7fdf2e:m:mgD9SPtnc4E7vH3JdnZAoIA

Matt,
The biggest issue that most digital scales have is that they will turn off after a certain amount of time due to inactivity. And when your adding chemicals to your mix there tends to be some inactivity while you open and close each of your different chemicals to add them in the mix. If you can shut this feature off on the scale then it shouldn't be a problem.

I got my digital scale from a fellow ex'er 12 years ago (?). he worked in the biz. He refurbished them on the side. It's a 10K with more functions then I know how to use. I think his name was Mark here is an email from 2007 holrum@HOTMAIL.COM

I just googled the email addy and it was Mark Sims

Sorry for not responding to this. I bought that scale and it seems to have done fine for me. I mixed a roughly 5kg batch to make a 98-4G motor and it performed fine. The propellant cured nominally, so the scale is accurate enough for me.

I have 2 scales, one for 2600 gram with a 0.1 gram accuracy and the other is a 7 kg with a 1 gram accuracy.
The smaller is used for everything except measuring the binder.
