Used with a suitable electronic balance for specific gravity determination of fresh and hardened concrete and aggregates. A purpose built robust frame designed to support the electronic balance. The lower part of the frame incorporates a moving platform, which carries the water container allowing the test specimens to be weighted in both air and water. The balance is not included and has to selected conforming to the weighing range required. Any type of electronic balance fit with an underbench weighing facility can be used as, for example, all our models. See Balances, electronic. The frame has to be completed with the 11-D0612/A1 cradle, to hold concrete cubes or cylinders, or with the suitable Density basket for use with aggregates.
