Used for the determination of the air content in concrete. This instrument directly supplies the rate of air contained in the form of bubbles in a pasty mass. The mix is subjected to a pressure that is twice that of the atmosphere, so that the volume of concrete which is uncompressible remains unchanged, while the volume of air is reduced to the half. The instrument is made from light alloy and it is supplied calibrated, complete with tamping rod and hand pump.
