Description
Concrete durability is essential in modern construction, especially in environments exposed to freezing and thawing cycles. One of the most effective methods to ensure this durability is through the use of an air entrainment meter. This precision instrument is critical in measuring the air content in freshly mixed concrete, helping engineers and quality control professionals verify that the mix meets design specifications for strength and resilience.
At CAPCO, we supply high-quality Air Meter Type B (8-litre capacity) units complete with calibration certification. Our air entrainment meters are designed to comply with international testing standards, offering accuracy, repeatability, and ease of use for construction professionals who demand reliability on-site.
Why Use Air Entrainment Meter?
Air entrainment meters are designed to determine the amount of air trapped within a concrete mix. This air is intentionally added during mixing through air-entraining agents and must be accurately measured to ensure the final concrete structure can withstand environmental stressors, particularly in colder climates. Excessive or insufficient air in concrete can significantly affect its strength and durability.
The Air Meter Type B/C is manufactured with a robust aluminum body and corrosion-resistant components, making it suitable for frequent use in tough conditions. With an 8-litre capacity and durable construction, this model meets the requirements of both BS EN 12350-7 and ASTM C231 standards.

Application in Quality Control
Testing air content is a vital part of quality control in concrete production. Too little air may lead to poor freeze-thaw resistance, while too much air can reduce strength. The air entrainment meter is a trusted tool among engineers, contractors, and quality assurance personnel. By ensuring accurate measurements, our meter supports the creation of concrete that balances workability, strength, and durability.
In colder regions, the presence of entrained air acts as a buffer against freeze-induced cracking. Each microscopic air bubble allows space for water to expand upon freezing, reducing internal stress and prolonging the life of concrete structures like bridges, pavements, and buildings.
How It Works
The air entrainment meter uses the pressure method for determining air content. After filling the base with freshly mixed concrete, the lid is clamped down and water is added to a specified level. A specific air pressure is then applied, and the amount of air in the concrete is read directly from a gauge. This test is non-destructive and can be completed on-site within minutes, making it an indispensable part of concrete testing procedures.

Calibration and Maintenance
Every unit of our Air Meter Type B/C – 8LT comes with a calibration certificate to ensure reliable accuracy. Regular calibration and proper maintenance are essential for continued precision. Components should be cleaned after every use, and seals inspected regularly to prevent leaks during testing.
At CAPCO, we not only supply the highest quality testing instruments but also offer guidance on maintenance and recalibration to ensure the long-term performance of your equipment.
Air entrained concrete gives increased resistance to weathering. It is important to accurately check air content to ensure that the correct amount of admixture has been used and that the concrete meets the required specification.
The Air Meter Type B is particular easy to use, the percentage air content reading comes directly from the pressure gauge. It has a sturdy aluminium construction with an 8 litre capacity. Quick release clamps and a built in pump make it easy and efficient to use.
The Air Meter Type B is supplied complete with a compacting bar, calibration equipment and instructions.
Compliant with EN12350-7 ISO1920.
We offer a calibration and repair service for all air meters, as well as supplying spare parts.
