Air Entrainment Meter Matest Made, 8 litres capacity, hand operated

The air content in fresh concrete is a critical parameter for assessing concrete's behaviour when exposed to weathering and for monitoring changes in air content resulting from applying chemical additives to enhance workability.

This apparatus, designed by Matest, determines the percentage of air contained in a fresh concrete mixture in accordance with a pressure-equalization process.
The device features an aluminium pressure chamber where air pressure is manually generated using an integrated hand pump. Upon opening an overflow valve, the system achieves pressure balance with the test pot, filled with fresh mortar or concrete.

The resultant pressure reduction serves as an indicator of the material's air content and appears on the connected pressure gauge.
The air entrainment meter can also be used to measure the unit weight of fresh concrete and aggregates.
