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.

Have you considered a ammo reloading scale? http://www.cabelas.com/tumblers-scales.shtml

They typically measure down to .01g and are fairly inexpensive.

We're not talking about mathematics, we're talking about cooking, a practical application of skills and applied sciences. It's entirely reasonable to call shenanigans on a request for a high-precision tool that costs peanuts. High-precision costs money. The ability to calibrate against a standard costs money. So, when someone questions the use-case, it's valid to provide a rationale.

You state ascorbic acid needs to measured in PPM; how is that typically managed? And by who? With what equipment? Comparing an industrial or laboratory situation to a home kitchen is absurd and disingenuous.

Your best bet is to find a used laboratory scale (ie. Metler) on the Internet for sale. Provided the scale is functional, it should be accurate for your purposes. Moving air can apply an amazing amount of pressure. If the scale does not come with a air hood, you will need to construct one if you want to have any success weighing to ±0.01 g. NOTE: These scales sell for a premium because drug dealers want them.

I use a Myweigh KD-7000 that I bought online. It's comparatively cheap and gives me a resolution of 0.05 ounces. I can't imagine any cooking application where you would need more granularity than that. It would be incredibly difficult to measure an amount smaller than that with any accuracy due to air currents adding noise to the reading.

One more thing - if you turn off the backlight on the display, the batteries last forever. I've had mine for years, using it every day (for my coffee at least) and I'm still using the original batteries that came with it.

Digital 0.01-gram resolution scales are plentiful and very inexpensive (< $20) on eBay and other online retailers. Most of them have a small, flat stainless steel pan, and tare for a container, making them convenient for use with small quantities of food.

I used one from eBay identical to this http://www.amazon.com/American-Weigh-Scale-Scalemate-Digital/dp/B0012TEQMG/ref=pd_sbs_indust_3 and was satisfied with the performance. Note that I was using it for balancing motorcycle pistons, a less demanding task than some others.

Note that you can also obtain scale weight sets for calibration.

I believe that general-use precision weighing of small, light-weight objects is a problem solved by any one of these small,inexpensive digital scales.

There is absolutely nothing in the world of cooking that requires accuracty to .01 gram. Even 0.1 gram accuracy is a bit much in the kitchen though I suppose if you are doing some molecular gastronomy stuff perhaps.

To want 0.01g accuracy for kitchen use is just plain silly. And honestly the only thing that goes that low reliably (this certainly won't do it http://www.amazon.com/American-Weigh-Scale-Scalemate-Digital/dp/B0012TEQMG/ref=pd_sbs_indust_3) is an anayltical balance that has an enclosure to shield it from air currents.

Here is one on ebay that is honestly a bit too cheap to really be reliable:

http://www.ebay.com/itm/600-x-0-01-GRAM-10-MG-DIGITAL-SCALE-BALANCE-LAB-ANALYTICAL-PRECISION-LABORATORY-/280805916405?pt=LH_DefaultDomain_0&hash=item4161563ef5

They usually cost $1,000 and up.

Here is a used one that was probably $3,000 new.

I've not found a 0.01g one (yet) that is cheap, accurate, and can be calibrated.

I usually like to have sensitivity to one decimal place more than I actually care about so I can see how far off I am from the target weight.

My 0.1g one http://www.scales-n-tools.com/index.php?main_page=product_info&products_id=113&zenid=7dq948nm1qgq59o6qr6c5iesm4 works fine in the kitchen (weighing tea, etc.) but I would also like one that is more sensitive for splitting human-dosed medicines (usually in capsules) down to cat-sized doses. Many medicines are 1/10 the cost this way.

I haven't found the solution yet, but all of you guys saying that a .01 resolution is unnecessary in a kitchen is missing something. Coffee. I need a .01 resolution.

Yes, ascorbic acid for conditioning bread dough is measured in parts per million. That's why I'm here.

In mathematics "I can't imagine" is not accepted as a proof of anything.

Furthermore to Syzygies disingenuous comment: If you are cooking bread on a commercial scale, say a 50 kilo batch you would need .05 grams (50 milligrams) of ascorbic acid if you wanted 1 part per million, barely doable with any reliability even on a good commercial scale.

For home cooking for say a two kilo loaf, if you needed 1 part per million of ascorbic acid now you are talking .002 grams (2 milligrams). This is at the limits of weighing even for a good, enclosed laboratory analytical balance and this is only with the following assumptions: you have recently calibrated the scale, it is on a solid granite vibration reducing table, you are not near a major highway (vibration).

So for anyone to think you can measure accurately to the 10 milligram level (.01 gram) on any scale for home use is just pure nonsense. And to assume that Syzygies could get anything approaching milligram accuracy on anything other than a lab analytical balance is just fooling yourself.
