Ultrasonic Concrete Tester AZA1151B
The Ultrasonic Concrete Tester (UCT – Model1151B) from AZA Lab is a fully portable, non-destructive testing instrument for assessing the strength and quality of concrete, either in-situ or precast. Designed with field conditions in mind, it combines simplicity, accuracy, and unmatched stability, making it ideal for construction sites, laboratories, and quality control applications.
The instrument generates low-frequency pulses and measures the time of flight through concrete. This time measurement is then used to calculate ultrasonic pulse velocity, which is directly related to the mechanical strength of concrete.

CHASE AIR INDICATOR AZA1105
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.

V FUNNEL AZA1111
AZA1111 V Funnel is a precision laboratory apparatus designed to measure the flow time and viscosity of Self-Compacting Concrete (SCC). It evaluates how quickly fresh SCC passes through a narrow, V-shaped section under the action of gravity, providing critical insight into the concrete’s workability, stability, and resistance to segregation.
The V Funnel test is essential when designing SCC mixes that must flow through heavily reinforced or congested formwork. By recording the time taken for concrete to completely discharge from the funnel, the apparatus allows engineers and technicians to quickly judge whether a mix is too stiff, too viscous, or optimally balanced.
Manufactured with a durable, corrosion-resistant metal body and a precise quick-release gate mechanism, AZA1111 ensures smooth, repeatable testing. Its rigid structure and stable stand make it suitable for both laboratory and site-based quality control environments.
