ULTRASONIC PULSE VELOCITY TESTER AZA1151

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.

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.

The AZA1126 Plastic Cube Mould is a precision-engineered solution designed for casting 150 mm × 150 mm × 150 mm concrete cubes used in compressive strength testing. Manufactured from high-impact, corrosion-resistant plastic, this mould offers an excellent balance of durability, ease of use, and portability—making it ideal for laboratories, construction sites, and training institutes. Its modular construction, consisting of detachable side walls and a sturdy base, allows for fast assembly and easy demoulding. The smooth internal surface ensures the concrete cube is removed cleanly without surface defects, supporting consistent, repeatable test results. Unlike metal moulds, the AZA1126 is lightweight, rust-free, and requires minimal maintenance, even in humid or coastal environments. The mould complies with IS 10086 and BS 1881-108, ensuring suitability for standardized concrete compressive strength testing procedures.

The AZA1119 Tamping Rod is a precision-engineered tool designed for proper compaction of concrete during laboratory and field testing. Essential for slump tests, cube/cylinder preparation, and unit weight determination, this rod ensures accurate removal of air voids, resulting in reliable and repeatable test outcomes.

Manufactured from hardened high-grade steel or stainless steel, the rod maintains dimensional accuracy, bending resistance, and a corrosion-proof finish. Each unit is polished to a smooth surface and features hemispherical ends to prevent mold damage and ensure uniform rodding action. The AZA1119 conforms to ASTM C143, ASTM C192, ASTM C138, IS 1199, and other major testing standards.

It is available in 16 mm and 25 mm diameters, with standard lengths of 600 mm (optional 450 mm). The rods are suitable for use in construction materials labs, QC departments, R&D centers, and field sampling units.
