Concrete Air Meters & Air Entrainment Testing Equipment
Choose a Pressure or Volumetric Air Meter
Pressure-type concrete air meters are widely used for routine air-content checks on normal-weight concrete. The Gilson Concrete Air Meter Kit with Gorilla Gauge is one complete configuration; a Volumetric Air Meter Kit serves a different measurement approach and specimen range.
Match the meter to the mixture being tested before ordering. Pressure methods have documented limitations for certain mixes, such as some lightweight aggregates, so verify the method requirements rather than assuming every meter suits every mixture.
Check the Supplied Components
Compare the contents list for each kit: gauge, clamping arrangement, flasks, scoop, strike-off bar, calibration vessel and carrying case are not identical across models. Replacement gasket kits and gauge calibration certificates are listed separately.
Inspect gaskets, clamps and gauge condition between uses. Follow the manufacturer's operating instructions for pressurizing, correction factors and reading the gauge; do not transfer operating steps or capacities from one meter design to another.
Plan Verification and Calibration
Confirm the calibration arrangement required by your procedure. A brass air meter calibrator is one listed option for verifying meter operation. Check the applicability of any correction factor for the aggregates in the mixture being tested.
Schedule verification against your laboratory's quality requirements and the governing test method. A calibration certificate documents condition at a point in time; it does not remove the need for periodic checks and careful technique.
Record Results and Complete the Fresh-Concrete Setup
Follow the specified sampling, consolidation, pressurizing and reading sequence, and record results with the batch information your quality program requires. Air-content readings describe the fresh mixture; they do not directly establish hardened-concrete strength.
For other fresh-concrete checks, browse fresh concrete testing equipment, including slump test kits and concrete thermometers. Select each instrument for the property it measures rather than expecting one device to cover every fresh-concrete evaluation.
