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.

CONCRETE FLOW TABLE TEST SET AZA1110
AZA1110 Concrete Flow Table Test Set is a precision-engineered laboratory apparatus designed to determine the workability, consistency, and flow characteristics of fresh concrete. It is especially suitable for Self-Compacting Concrete (SCC), precast concrete, and high-consistency mixes where the traditional slump test is not effective.
This test set works by allowing a freshly mixed concrete sample to spread under controlled, repeated vertical jolts of a mechanically calibrated table. The final spread diameter of the concrete is measured to assess its flowability and uniformity.
Built with a rigid, precisely machined table surface, the AZA1110 ensures repeatable and reliable results. Its heavy-duty construction allows long-term use in demanding laboratory environments while remaining easy to clean, store, and maintain.
The apparatus complies with major international standards including IS 1199, ASTM C1437, and BS EN 12350-5, making it suitable for both domestic and international testing requirements.

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.
The equipment is designed in compliance with EN 12350-9 and EFNARC guidelines, ensuring globally accepted and repeatable test results
