Q&A

Specific Gravity Bench allows easy suspended weighing of samples in water for relative density determinations of aggregates, hardened concrete, bituminous mixtures, refractory brick, and similar materials. The bench is sturdy 0.15in steel, and features one 3.5in (88.9mm) diameter hole in the top balance platform for weigh-below hook suspension of samples and thermometers.

The lower support doubles as a shelf that can be adjusted to fit heavy-duty polyethylene 30gal (114L) or 45gal (170L) Plastic Water Tanks (ordered separately). The tank can be positioned at either 4 or 10in above the ground (without casters). Water heater and circulator accessories can be added to the tanks for precise temperature control of immersion water. Wire baskets and cradles in small and large capacities are also available for suspended weighing.

The balance accessory offers versatile solutions in parts counting, percent, and differential weighing, density determination, statistics, and more.
