The proper control of entrained air in concrete is recognized as one of the most important functions in modern concrete manufacture. To the concrete engineer and technician, the Air Entrainment Meter offers an instrument for use in the testing and designing of concrete mixes.
The instrument is designed so that the operating parts form an integral unit. The container is rigid, thereby providing an accurate device for the performance of unit weight testing. For convenience, the tare weight in grams is stamped on the bottom. When used with the supplied monograph, the air meter provides quick and easy particle density and percent of free moisture in aggregate determinations.
The meter has a multi-range feature to accurately measure entrained air up to 22%. It is supplied complete with straight edge, syringe and carrying case.
Applicable Standards: EN 12350-7; ASTM C 231, ASTM C 213, AASHTO T-152.
