Air Entrainment Meters for Mortar

Air entrainment meters for testing freshly-mixed mortar with direct readings in percent. Uses a hand-operated pump.

These air meters are used for the determination of the total air content in cement paste, mortar, and masonry cement. These meters have a pressure chamber in which a defined pressure is generated. By opening the overflow valve, the pressure in the chamber is equalized within the sample container, which is filled with mortar. These air meters use pushbutton controls for simple test operation. The pressure drop is a measurement of the air content present in the mortar. The accuracy of the pressure gauge is 1.0.

All three air meters use pushbutton controls for simple test operation. These meters use a mechanical valve to provide a reliable seal between the pressure chamber and test container. The pressure gauge is integrated in the top of the meter. Quick-release fasteners between the container and cover provide easy sealing and opening of the meter.

All three air entrainment meters utilize a robust hand pump for operation independent of the air supply system.
