(or food scales in general); in fact, I've never even seen one in the

You should go to a store and try.
Nowadays, you get for cheap excellent digital kitchen scales 1g to 2 or 5
kg, with a precision of 1g for the first 500g. The little battery lasts 2
years at least (it's still the original one for me). You have a button to
reset at zero after you place the saucer or piece of paper on which you put
the tea and imediatly read the weight. For cooking, you can place a bowl and
add successively each ingredient, just resetting zero each time.
My scale weights food, mail, tea, etc. Take the 5 kg model if you have a big
family (may have to weight whole chicken, etc).

You are not in the tea business, are you ? They spend the day weighting tons
of tea. They need scales much more resistant, but not really more precise
than the home kitchen equipment.
