DE-MOUNTABLE MECHANICAL STRAIN GAUGE AZA1170

AZA1105 Chase Air Indicator is a compact, lightweight, and highly practical field instrument designed to measure the air content in freshly mixed concrete. It is widely used in construction sites where rapid quality decisions are required and laboratory testing equipment is not readily available.

This device serves as a reliable field alternative to standard air content methods such as ASTM C231 (Pressure Method) and ASTM C173 (Volumetric Method). While it is not intended to replace laboratory-grade instruments, it provides fast, useful guidance that helps engineers and site supervisors maintain proper concrete mix quality.

Air entrainment plays a critical role in concrete durability, especially in regions exposed to freeze–thaw cycles, and contributes significantly to workability and pumpability of concrete. AZA1105 helps ensure that air content remains within the recommended range (typically 4%–7%), reducing the risk of weak or brittle concrete.

The working principle is based on fluid displacement and vacuum pressure balance. A representative mortar sample is collected and placed inside the testing chamber, where a controlled vacuum is applied. The internal pressure difference is translated directly to a calibrated dial gauge showing the approximate air content percentage.

With no electrical components, moving mechanical assemblies, or complex maintenance requirements, the AZA1105 is extremely reliable and built for tough field conditions. Its rugged body and easy-to-read dial make it suitable for continuous daily use in real-world jobsite environments.
