Air entrainment meters for testing freshly-mixed mortar with direct readings in percent. 使用手动泵.
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.
