AIR ENTRAINMENT METER

Air Entrainment Meter

Product Code: MSI 2066 (Series MSI 2066A to MSI 2066D)

The Air Entrainment Meter is a professional-grade precision testing instrument designed to determine the percentage of air entrained in freshly mixed concrete using the standard pressure method. Fully compliant with IS 1199 (1959) and BS 1881-106, this testing process is critical because limited air entrainment improves concrete durability, while incorrect percentages significantly degrade strength. It is an indispensable tool when using workability-enhancing chemical additives, which require rigorous air content monitoring.

The apparatus features a heavy-duty, pressure-tight flanged cylindrical measuring bowl securely connected to a removable flanged conical cover assembly via a leak-proof seal. The top cover is fitted with a built-in air valve and bleeding petcocks. A clear, graduated transparent standpipe directly displays the live air content percentage. Air pressure is introduced safely via a hand pressure bulb and tracked using a rugged pressure gauge mounted directly onto the standpipe assembly.

🎯 Applications

• Air Content Quantification in Freshly Mixed Concrete

• Workability Additive & Chemical Admixture Verification Audits

• Concrete Durability & Freeze-Thaw Resistance Assessment

• Civil Engineering & Concrete Material Calibration Laboratories

• Ready Mix Concrete (RMC) Quality Control Plants

• Highway, Dam, and Airport Runway Infrastructure Projects

⭐ Features

• Multi-Standard Compliance: Fulfills the strict pressure method testing protocols of IS 1199 and BS 1881-106.

• Leak-Proof Sealed Flanges: High-pressure flanged clamping interfaces prevent air or fluid bleeding during pressurization cycles.

• Direct Graduated Standpipe: Clear vertical standpipe provides a direct visual reading of air content percentage without complex manual calculations.

• Integrated Pressure Controls: Equipped with an easy-to-use hand pressure bulb and a fine-graduated pressure gauge for precise pressure regulation.

• Comprehensive Accessory Kit: Supplied ready-to-use with a calibration cylinder, spring clamp, trowel, standard tamping rod, straight edge, rubber mallet, and volumetric measure.

• Versatile Capacity Range: Available in four configuration options with capacity loads scaling up to 0.01 cubic meters.

🔬 Working Principle

Fresh concrete is placed into the cylindrical measuring bowl in standard compacted layers and leveled off flush using the straight edge [MSI 2022]. The conical cover assembly is clamped securely onto the bowl flange, creating a tight seal. Water is introduced through the petcocks until it fills the space above the concrete and rises inside the graduated transparent standpipe.

The petcocks are closed, and the hand pressure bulb is used to introduce air pressure into the chamber. This applied pressure compresses the entrained air bubbles trapped inside the concrete mix, causing the water level in the standpipe to drop. The change in the water level directly corresponds to the percentage of air entrained in the concrete, which is read immediately from the graduated scale.

💡 Advantages

• Optimizes concrete life expectancy by helping technicians hit exact air entrainment parameters to resist weathering.

• Eliminates calculation errors with a direct-reading visual standpipe that maps out exact percentages on-site.

• Heavy-gauge cast metal build prevents structural flexing under pressure, ensuring highly accurate and repeatable test logs.

• Complete, all-in-one delivery setup saves costs by including all required tools and calibration equipment in a single package.
