AZA 1148 CONCRETE TEST HAMMER (SCHMIDT HAMMER) N TYPE

Description

Concrete Test Hammer (Schmidt Hammer) N Type is a widely used, non-destructive testing instrument for determining the compressive strength of hardened concrete. It operates on the rebound principle, where a spring-loaded mass impacts a concrete surface and the rebound value is measured, indicating the surface hardness and indirectly the strength of the concrete.

This N-Type hammer is designed for general testing of concrete in construction sites, laboratories, bridges, tunnels, and industrial buildings. With an impact energy of 2.207 Nm, it is suitable for concrete structures with compressive strength between 10 and 70 MPa. It provides a quick and cost-effective way to estimate in-place strength without damaging the concrete structure.

Constructed with a lightweight yet durable aluminum body, the hammer is ergonomically designed for prolonged use in field conditions. The internal components are precision-engineered to deliver consistent impact force and accurate rebound readings. The plunger tip is made from hardened alloy steel to withstand wear over extended usage.

Each concrete test hammer comes calibrated with a factory certificate, ready for immediate deployment. The calibration is traceable to national standards and aligned with the requirements of ASTM C805 and EN 12504-2. These standards ensure reliable and repeatable results across various testing environments.

Applications include routine quality control, structural health monitoring, and comparative strength assessment of concrete. It’s especially useful when core extraction or destructive testing is not feasible. In civil engineering projects, early detection of low-strength areas can prevent costly failures and ensure structural safety.

This Schmidt Hammer N Type is ideal for field technicians, engineers, and researchers. The rebound number (R-value) displayed on the scale is used to correlate with compressive strength through standard calibration curves. A conversion chart is provided, and users can also customize correlation graphs based on local conditions and aggregate types.

The package includes a grinding stone for surface preparation, ensuring consistent contact between the plunger and test surface. A sturdy carrying case protects the instrument during transport. Optional accessories like digital readers and data loggers are available for enhanced data recording.

Maintenance is simple—routine cleaning and checking of rebound consistency using a reference anvil keep the device reliable. AZA-LAB offers periodic recalibration and servicing to maintain compliance with testing standards.

In conclusion, the Concrete Test Hammer N Type is an essential tool for non-destructive strength evaluation. It balances portability, accuracy, and ruggedness, making it an indispensable part of any construction material testing toolkit. Whether you’re monitoring structural integrity or verifying concrete grades, this hammer delivers dependable performance under real-world conditions.
