Mineralab developed an above the scale underwater weighing process, along with a Universal Specific Gravity Kit (see video). Just weigh the stone “in air” on the integrated weighing platform of the scale, then without changing any setup, weigh the stone in water by placing it in the underwater weighing pan suspended above the platform. Then plug those two values into the Specific Gravity equation to obtain the specific gravity of your material. It’s that easy and it takes only a few seconds. PRICE DOES NOT INCLUDE SCALE.
