Air Entrainment Meters for Mortar

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

The H-2845 and H-2846 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. The pressure drop is a measurement of the air content present in the mortar. The accuracy of the pressure gauge is 1.0.

Both air meters use pushbutton controls for simple test operation. Both 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.

Both meters utilize a robust hand pump for operation independent of air supply system.

H-2845: 1 liter volume — EN 1015-7 and EN 459-2
H-2846: 0.75 liter volume — EN 413-2
