* 0.01 accuracy, I am using a mechanical one that I have had since college, it has a capacity of 410 grams, and is good for chemicals. If I was commercial I would have a $4K mettler that does 5000 grams
* 0.1 kilo accuracy/ 100 gram the bathroom scale lives in the wine area in harvest season. If I was commercial I would have a stainless platform scale with a detachable read out and 500 kg capacity
* my 5000 gram/ 5kg is an ordinary kitchen scale but it was $3 at StVinnies.
Today cheap digital balances work well/ are readily available/ are compact/ are reasonably rugged. The only balance to be questioning is the 0.01 accuracy, the rugged ones are price. Assume that you will spill on your balance therefore stainless is good
