Wide-Range Mortar Air Entrainment Meter – ToronMAM™ WR
ToronMAM™ WR is a precision direct-reading mortar air content meter that integrates German sensing technology for high-accuracy measurement of entrained air in fresh mortar mixes. Designed specifically for ordinary mortar and CA mortar applications, this instrument offers an exceptionally wide measurement range of 0% to 100% — making it one of the most versatile mortar air testers available for use across diverse mortar types and mix specifications.
Built from a magnesium-aluminum-silicon alloy body with a dustproof, waterproof, and explosion-proof pressure gauge, the ToronMAM™ WR is engineered for demanding field conditions where standard instruments may fall short. The press-type snap buckle closure provides a fast, secure seal on the 1-liter bowl, and the instrument weighs approximately 6 kg — balancing durability with portability. For laboratories and construction teams working with a wide range of mortars, this air meter offers the precision and range needed for comprehensive air content verification.

Theory and Method
The ToronMAM™ WR operates on the direct-reading pressure method for determining entrained air content in fresh mortar. The mortar sample is placed in the sealed 1-liter bowl and the press-type buckle is secured. Air pressure is then applied to the chamber above the sample. When the equalization valve is opened, the pressurized air compresses the entrained air voids within the mortar, and the resulting pressure change is read directly from the gauge as a percentage of air content — no charts, no curve plotting, and no additional calculation steps.
The German sensing technology at the core of this mortar air meter delivers stable, high-sensitivity pressure readings across the instrument's full 0% to 100% measurement range. Graduated accuracy tiers — ±0.1% for 0%–5%, ±0.15% for 6%–20%, and ±0.2% for 21%–100% — ensure that results remain meaningful and trustworthy across both low and high air content mortar mixes. Note that the pressure gauge does not support MPa-unit testing and is calibrated exclusively for percentage-based air content readout.
