Thanks for the tip.

It seems that the Ohaus hanging pan balances have the advantage of
reading to 0.01 g. The triple-bream balances have the advantage of
holding large beakers or graduated cylinders and can read as high as
2.6 kg, though only as low as 0.1 g.

I decided to go with the hanging pan balances for the precision and
to purchase one triple-beam balance for those instances when it's
needed.

Thanks again,

Aaron
