Hello,

What is the best digital scale that dependably measures items to 0.01 gram precision? I'm l looking for something food-safe, to be used in the kitchen. It doesn't have to be waterproof as such, but should be easy to clean with a towel.

TIA!

P.S. Most kitchen digital scales only measure to 1 gram resolution. I need higher granularity for measuring out small amounts of spices and cultures.

Checkout Digiscale Kitchen Scales. They are 0.1 oz/1 gram precision. However, not ".01"

In addition, you don't weigh ascorbic. It comes in tablets on a carrier to increase its size. You calculate the number of tablets based on ppm desired in the formula and pounds of flour in the batch size to determine the number of tablets required. Scales with divisions of smaller than 1g are significantly affected, as others here have noted, by vibration and air currents. Another factor mentioned is absolutely true, you get what you pay for. Cost is based on number of divisions and accuracy of the scale. If something in scales is to inexpensive to believe, it is probably sacrificing quality and accuracy.
I weigh and grind my own coffee as well and an accurate 0.1g scale is all that is needed. Same with any other ingredient in the kitchen, unless, of course, you're preparing for Barbie, but then accuracy won't be nearly as important as a constant supply of 4 watt bulbs for your little pink oven. ;-)

I’ve used a torbal BTA model. It has a 0.01g resolution which is what you are looking for, but only 200g capacity which sometimes is not enough, other than that the scale works really well. I’ve had it for over a year now and no issue. It’s relatively easy to clean; it has a sealed front panel. I bought this thing on sale for around $300 - http://www.torbalscales.com/industrial/precision-general-purpose/precision.html

Uhhh, to the most recent poster, from the specs of the scale you are advocating as a solution:

Precision (g)- +/- 0.01

Click on the specifications tab of the product.

Thus, it measures to .01 grams, give or take .01 grams. i.e. you can not measure with any reliability to .01 grams.

You DO need an analytical balance to get that kind of precision.

You don't need an analytic balance to do 0.01 grams. I regularly use one in my classroom. This one http://www.flinnsci.com/store/Scripts/prodView.asp?idproduct=20596 sold by Flinn isn't cheap but I've used its equivalent for years with good results.

The key idea for a scale is the ratio of precision and accuracy to capacity. Cheap scales can be precise but rarely have much capacity. More expensive scales are precise and can measure a lot of weight.

I also occurs to me that you would get MUCH more reliable mixing by dissolving your ascorbic acid in water and using the water to make your bread.

Use the same 1:20, and then 1:400 ratios and I bet you can get much closer to your desired amount.

I apologize for the "disingenuous" comment. Sounds like you could teach me a thing or two about mixing.

I find often on teh internets there are folks out there raving about some nerd tech fetish object without really understanding the principles behind them. Clearly that is not the case here.

I actually posted a review on an excellent scale for postal use etc elsewhere on this board, but not at all what you are looking for.

Still not sure I understand the utility of the .01 gm readout if it is easily off by 50% or more. (Just for clarification, I'm not being disingenuous here ;-), how is it more useful than a scale with say a .1 gm readout that is in fact accurate?

P.S. I just pulled your publication and will give it a read.

@striperguy, I provided the details of my baking to illustrate that my comment wasn't disingenuous, nor was I fooling myself. Do you ever retract statements in light of new evidence? I'm aware of mixing issues; the cutoff phenomenon as observed in industrial mixing processes was first proved to exist in the paper "Trailing the Dovetail Shuffle to its Lair", of which I am a coauthor.

Another home application for the best scale one can readily obtain is mixing beverages. There's a current revival of old school sodas, for example. Try mixing a cola recipe without accurate methods for working with small quantities.

The way to call shenanigans here is to empirically test the best reviewed affordable scale of this type. Is it worth the money, if one already has a scale one trusts to 2 gram accuracy? It is a freshman mistake to confuse precision with accuracy. I want a 0.01 gram readout, I dismiss the sales pitch without taking offense, and I'll work with whatever accuracy I can get. What's the best affordable scale out there? It's just a tool, and affordable tools generally make demands on the competency of the user.
