The Qualitest Advanced Air Entrainment Meter is used to measure the air content of freshly mixed mortar in accordance with the air pressure compensation principle. The Air Entrainment Meter has a pressure chamber in which a predefined pressure is generated. When the overflow valve is opened, the pressure is compensated with respect to the test pot, which is filled with the freshly mixed mortar. The pressure drop is measured to give the air content in the mortar.
Air entrainment is the intentional creation of air bubbles in concrete or mortar. Excess water is often trapped within the mix as it hardens. The excess water eventually evaporates and leaves behind porous cavities. These pores create weaknesses in the concrete or mortar during freeze-thaw cycles. An air entrainment meter is used to measure the amount of air that is trapped within the mix. The sleek design of each of these units allow for easy storage on top of any workstation.
Qualitest offers Air Entrainment meters in different capacities adhering to DIN EN 459-2; DIN EN413-2; ASTM C 185 and other international standards. These meters are either with a sturdy hand-operated pump or with an electrical mini compressor for rapid and uniform provision of pressure.
QUALIAEM-A1M Automatic Air Entrainment Meter 1L was designed to be efficient and easy to use for mortars. The built-in miniature air compressor is the perfect upgrade from the traditional manual pumps. This design also ensures that the operator doesn’t require extensive training or technical expertise. The large central meter ensures that the results and reading can be done effectively, easily and without strain. The automated process also allows for great time savings and efficiencies in that it frees up the operator to attend to other tasks
QUALIAEM-A8 & QualiAEM-M8 Air Entrainment Meter was designed to be efficient and easy to use. The built-in miniature air compressor is the perfect upgrade from the traditional manual pumps. This design also ensures that the operator doesn’t require extensive training or technical expertise. The large central meter ensures that the results and reading can be done effectively, easily and without strain.
The automated process also allows for great time savings and efficiencies in that it frees up the operator to attend to other tasks with the QUALIAEM-A8.
The manual Air Entrainment Meter design model QUALIAEM-M8 takes the best of the traditional machine and infuses it with a more modern look. It is the same, tried and true operation but with a sleek vessel and sturdy construction. Both units are built to last and would become the new work horses of your testing equipment. Another manual Air Entrainment Meter design is the QUALIAEM-M8I model for Concrete.
Features of the Air Entrainment Meter
- Extreme sturdiness
- Simple operation
- Great accuracy
- Designed for ease of service
- Pressure gauge with Class 1.0 accuracy
The Air Entrainment Meter is made of cast aluminum; locking bolts with palm grip give the test pot and upper section an airtight seal. Two ball cocks are provided to fill the required water and to vent the air. The air is compressed by means of a built-in hand pump. The connection valve for the initial pressure and the overflow valve are integrated into the pressure chamber. The connection valve is a sensitive needle valve with a knurled head screw. The over flow valve for the pressure compensation between the pressure chamber and the test pot is operated by means of a valve rocker. The pressure valve is installed directly on the pressure chamber and the scale shows readings with a range of 0-100 vol%.
