  Description
  This is a lightweight model of the Roll-A-Meter. The device accurately measures air content of concrete mixes. It is also used to test lightweight aggregate concrete. The anodized aluminum version weighs 10.5 lb (4.8kg), less than half the weight of the bronze models. Base and top are fastened with quick-acting clamps after concrete sample is placed in the base. Water and isopropyl alcohol are added to zero mark on meter's neck, and the meter is inverted, rolled, and rocked until air is removed from the concrete mixture. Percent of air is read directly from liquid level on the meter's scale.

The lightweight Roll-A-Meter may be used as a pycnometer for determining specific gravity of sand, gravel, and cement.
