We are currently using a Vernier Force Plate from www.vernier.com to measure
weights, structural strength and force. This device must to be connected to
a data collection device like a computer or PDA type device. This scale will
measure in Newtons and pounds. The range is 1/100th of a pound to over
200lbs. It is very durable and can be used for both compression and tension
force measurements.

Subject: Durable Scale for Weighing Objects?

Any suggestions for a good durable scale which visitors could use to
weigh things they build?  We are designing an exhibit where kids will be
building/inventing all sorts of projects.  The approximate weight range
might be from a few ounces to a handful of pounds (maybe 5 tops?)  We
want the kids to be able to record various measurements and weight is
one of them.  They will be mounted on a table top so it will not be
likely that kids will stand on them (famous last words...) but we would
like there to be some finess since one aspect of use might be in how by
shaving off weight their invention might perform better.
 
Trying not to reinvent (or re-research) the wheel here. Any response is
appreciated.
