Air entrainment meter for freshly mixed concrete, with manually operated pump. This meter measures the air void content in fresh concrete and directly shows this content on a pressure gauge in percent.
Testing Capacity - 8 litres
The equipment operates according to the pressure equalisation method. The test equipment has a pressure chamber, in which a defined pressure is generated. By opening an overflow valve, the pressure in the chamber is equalised with the pressure in the sample container, which is filled with concrete. The pressure drop is a measurement of the air content in the concrete. The pressure gauge is accuracy class 1.0 and is very clearly arranged.Direct reading in percentage

The line scape of the pressure gauge for the 8 L equipment is graduated as follows:
0 - 8 % by vol. 0.1 % vol. per scale division
8 - 15 % by vol. 0.5 % vol. per scale division
15 - 20 % by vol. 1.0 % vol. per scale division
20 - 50 % by vol. 5.0 % vol. per scale division
50 - 100 % by vol. without graduation
