An air content meter measures the amount of entrained and entrapped air in fresh concrete. Accurate air content is critical for freeze-thaw durability, workability, and strength — and must be checked on site and in the laboratory to meet mix design and project specifications.
The air content meter determines the percentage of air by volume in a fresh concrete sample. Two common methods are used: the pressure method, which measures the change in pressure in a sealed vessel when the sample is compressed, and the volumetric method, which measures the volume of air displaced from a known volume of concrete.
Air content meters are used on construction sites and in testing laboratories to verify that air-entrained concrete meets the required air content for its exposure conditions. Correct air content improves freeze-thaw resistance, workability, and resistance to de-icing salts.
Meters are available in different sizes for different maximum aggregate sizes, and in pressure or volumetric configurations. They are supplied with calibrated gauges, sealing clamps, and accessories for accurate, repeatable measurement.
J.R. Machinery India supplies air content meters engineered for accurate, standards-compliant measurement of air in fresh concrete. Our meters feature rigid vessels, calibrated gauges, secure sealing systems, and durable construction. Options are available for different sample sizes and measurement methods to suit specific testing and project requirements.
