Air Content Meter Calibration for Fresh Concrete
Air content meters for fresh concrete are used in quality control of concrete mixes, particularly with respect to workability, durability and structural resistance. A properly adjusted and calibrated instrument is essential for reliable determination of the air volume in concrete according to the requirements of technical standards.

Metrological activities for air content meters
- Calibration of air content meters for fresh concrete according to STN EN 12350-7.
- Functional check and assessment of technical condition; if required, cleaning of the vessel from cement and concrete residue (price according to the current price list).
- Determination of the volume of the test vessel for fresh concrete density tests by the gravimetric method, up to 10 dm³.
- Calibration of the air-content scale in the range from 0% to 10% of air volume in the test vessel.
- Calibration at 7 calibration points.
- Determination of air volume in the test vessel by the gravimetric method, ensuring traceability to mass and volume standards.
- Evaluation of measurement results and issuance of a calibration certificate.
Which instruments we calibrate
We calibrate pressure-type air content meters for fresh concrete, also known as air entrainment meters or pressure gauge type air meters. The service can also include cleaning of the vessel from cement and concrete residue.
