Press-Ur-Meter Concrete Air Meter
Supports the following standards: ASTM C192, ASTM C231, AASHTO T152
This is the original Press-Ur-Meter for field and laboratory tests. This air meter is designed to provide air content and the determination of specific gravity and free moisture of aggregate. Designed to save time, reduce water use, ensure accuracy and maintain sample integrity (sample may also be used for slump and compression tests).
The meter uses brass cover clamps, which can be adjusted for clamping pressure. A large, easy-to-read, 4″ diameter, direct percentage gauge with calibration adjustments is accurate to nearest 0.1%.
The H-2786 meter also features the Humboldt, all-brass super pump (H-2785.DB), the most reliable and highest-quality pump available. The meter’s base/bucket can be used as a 0.25 cu. ft. unit weight measure.
