Dear Jim and All, Your kitchen scales look to be an updated version of my old Salter Model 323. Mine has a stainless steel platform (170mm by 150�mm) and it appears to have four load cells. Ours sits permanently on our kitchen bench and it is invaluable for bread baking � I even 'weigh' the water!
The Salter Model 323 has a resolution of one gram from 2 grams to 5000 grams; it refuses to indicate masses below 2 g so I like your idea for finding the mass of the almonds.
