Lightweight Roll-A-Meter for Concrete Mixes
Lightweight Concrete Roll-A-Meter is a lightweight version of the popular roller meter. It’s a simple and accurate device for measuring the air content, including entrained air, of concrete mixes. It’s required for use with lightweight aggregate concrete, but can be used with any mix and strike off bar. The lightweight hard-anodized aluminum version is less than half the weight of earlier bronze models. The base and top are highly scratch and wear-resistant and fastened together with quick-acting stainless steel clamps. Water and isopropyl alcohol are added to the zero graduation on the neck, and the meter is inverted, rolled, and rocked until the air is removed from the concrete. Percent of air is read directly from the liquid level on the scale. Accurately determining the liquid level is crucial for proper mixing and quality of concrete, especially for lightweight aggregate mixes.
The see-through window in the neck, engraved with a clear scale graduated from 0 to 9% with .25% sub-graduations, allows for easy and accurate reading of the air content, so your mixes meet the specs.
The Roll A Meter can also be used as a pycnometer to determine the specific gravity of sand, gravel and cement. Unit comes in foam-lined plastic carrying case with Strike Off BarTamping Rod, Syringe, Baffle-Bottom Funnel and instructions. The strike bar and the unit has a 130in³ (2,130ml) base volume and a maximum diameter of 8in (203mm).
