Model: ON BALANCE OB-3000
We use one of these ourselves, in the laboratory where we manufature gold testers. We lost it!! So I took a new one from stock. The original turned up the next day but now I have one that has marks on the weighing platform so I have to sell it as, "second hand". Apart from the marks, it is like new, including its box. Guaranteed until July 2020.
Incidentally, you notice that of all the balances we sell, we choose to use this model ourselves, that's a sign that this is a good scale!
Weighs down to 0.1g and up to 3000g, can be switched to Troy ounces for weighing silver.
Suitable for weighing both gold and heavy silver items (3000g = 3Kg = about 96oz)
