Description
H-2783A
Humboldt Concrete Air Meter
Supports the following standards: ASTM C231, ASTM C31, ASTM C192, AASHTO T152
Concrete air meters determine the amount of entrained air in freshly mixed concrete. This measurement ensures the concrete’s durability, workability, and resistance to freeze-thaw cycles.
Concrete air meters, also known as air entrainment meters, measure the air content of fresh concrete, which is the volume of air bubbles trapped within the concrete mix.
Air entrainment is a vital process in concrete, as it improves the concrete’s ability to withstand freeze-thaw cycles, reduces scaling caused by deicing chemicals, and enhances workability.
Air meters typically use pressure or volumetric methods to determine the air content. Pressure meters, for example, apply pressure to a concrete sample and measure the resulting change in volume to calculate the air content.
The meter’s easy-to-use, extra-durable stainless steel clamping system employs four one-piece, self-locking clamps that quickly seal the lid to the base with proper tension, aided by an o-ring to assure a watertight seal. The large, easy-to-read, 4-inch diameter, heavy-duty, direct percentage gauge with calibration adjustments is accurate to the nearest 0.1%. The bucket, or pressure chamber, features EZ-grip, cast handles, which improve usability. This is especially true when the bucket is also used as a 0.25 cu. ft. unit weight measure. The lid of the pressure meter features a smooth sloped top so water and concrete wipe right off. By eliminating the cavities in the lid that trap and hold concrete, maintenance and repair problems are greatly reduced.
