DIGITAL PULL-OFF ADHESION TESTER AZA1152
The AZA1152 Digital Pull-Off Adhesion Tester is a professional, high-accuracy instrument engineered to evaluate the bond strength of coatings, paints, sealants, and adhesives applied to various substrates including concrete, metal, wood, plastic, stone, and composites. Designed for field and laboratory environments, it delivers reliable, repeatable, and standards-compliant adhesion measurements across construction, marine, automotive, industrial coating, and civil engineering sectors.
This device utilizes the pull-off testing principle, where a precision-machined dolly is bonded to the coating surface and a controlled tensile force is applied until failure. The tester records the exact force required for detachment, providing a direct measure of adhesion strength and enabling analysis of failure modes (adhesive, cohesive, or substrate failure).

L SHAPE BOX APPARATUS AZA1112
AZA1112 L Shape Box Apparatus is a precision testing device designed to evaluate the passing ability and flow performance of Self-Compacting Concrete (SCC) in congested reinforcement conditions. This apparatus simulates real-world scenarios such as densely reinforced beams, columns, tunnels, and bridge segments, where concrete must flow freely without segregation or blockage.
The distinctive L-shaped design creates a controlled flow path where freshly mixed SCC moves from a vertical chamber into a horizontal channel containing reinforcement bars. By measuring the concrete heights at both ends (H1 and H2), the H2/H1 ratio is calculated, providing a direct, quantitative assessment of the concrete’s ability to pass through obstructions.
Manufactured from durable, corrosion-resistant steel, AZA1112 is built for long-term laboratory and site use. It conforms to EN 12350-10 and EFNARC guidelines, ensuring global acceptance of test results.
PLASTIC BEAM MOULD AZA1128
The Azalab AZA1128 Polyurethane Beam Mould Series is engineered for casting concrete beam specimens used in flexural strength tests.
