Digital Concrete Air Meter – ToronCAM™ D
ToronCAM™ D is an advanced direct-reading concrete air meter featuring a bilingual digital display that delivers clear, precise air content readings without the interpretation challenges associated with analog gauges. Designed for both field and laboratory use, this concrete air tester is powered by a rechargeable lithium battery — providing operational independence from power outlets on any jobsite.
Constructed from a magnesium-aluminum-zinc durable alloy with copper operating valves, the ToronCAM™ D air entrainment meter combines structural durability with measurement precision. Its imported ceramic sensing chip and 0.2 MPa maximum pressure gauge range deliver greater accuracy than conventional analog instruments, with a test error of approximately ±0.0020% across the full 0% to 10% measurement range. For teams that demand digital confidence in their air meter for concrete testing, the ToronCAM™ D sets a new standard in the field.
Digital Concrete Air Meter – ToronCAM™ D Applications
The ToronCAM™ D concrete air meter is well suited for use in the following industries and project types:

- 7,000 mL measuring bowl: standard capacity for fresh concrete samples per ASTM and international test methods
- Maximum aggregate particle size compatibility of 40 mm: wide mix design applicability
- 0.2 MPa maximum pressure gauge range: greater operating range than standard analog meters
- Factory pre-calibrated initial pressure point of 0.1000 ± 0.0020 MPa: traceable, consistent test setup
- Dry method (no water) support: initial pressure point 0.1000 MPa with ≤10 last-digit fluctuation
- Manual sliding air exhaust: controlled and reliable pressure release during testing
- Universal bubble level: ensures accurate instrument leveling as required by standard test procedures
Theory and Method
The ToronCAM™ D operates on the pressure method — the globally recognized standard for measuring air content in freshly mixed concrete. The concrete sample is sealed within the 7,000 mL measuring bowl, and a pre-calibrated initial pressure of 0.1000 ± 0.0020 MPa is applied via the air chamber. When the equalization valve is opened, the pressure differential caused by the entrained air voids in the concrete is measured by the ceramic sensing chip and displayed digitally as a percentage of air content.
This air meter for concrete also supports a dry method (initial pressure without water), where the initial point reads 0.1000 MPa with a last-two-decimal-digit fluctuation of ≤10. The manual sliding air exhaust method provides controlled pressure release. All initial pressure points are factory pre-calibrated and can be adjusted for environment and operator preferences, maintaining consistency across different test conditions without recalibration in the field.
