High-Precision Concrete Air Meter – ToronCAM™ HP
ToronCAM™ HP is a precision direct-reading concrete air meter that incorporates Sanyo technology sensing components from Japan for high-accuracy air content measurement in freshly mixed concrete. Designed for construction projects requiring concrete across the C15 to C80 strength range, this air entrainment meter delivers reliable readings in a rugged, field-ready package. Its durable alloy body, dustproof and waterproof pressure gauge, and all-copper valve assembly make it a dependable concrete air tester for both plant and jobsite use.
With a 7-liter bowl capacity, a measurement range of 1% to 10%, and an accuracy of ±0.1%, the ToronCAM™ HP air meter for concrete is well suited for quality control teams who demand precision without sacrificing portability or durability. The explosion-proof, waterproof pressure gauge design adds an extra margin of safety for high-frequency use on active construction sites.

Theory and Method
The ToronCAM™ HP operates on the direct-reading pressure method for measuring entrained air in fresh concrete. The concrete sample is sealed within the 7-liter bowl, and a controlled initial air pressure is applied. When the equalizing valve is opened, the pressure drop caused by the compression of entrained air voids in the concrete sample is read directly on the gauge as a percentage of air content — providing immediate results without the need for charts or computation.
The Sanyo-technology pressure sensing system from Japan delivers high sensitivity and stability, making this air meter concrete testing instrument suitable for precision applications across the full C15 to C80 compressive strength spectrum. The instrument's dustproof, waterproof, and explosion-proof gauge housing ensures consistent performance in challenging field environments where conventional gauges may be susceptible to contamination or damage.
