Product Description
The digital concrete rebound hammer is an advanced, non-destructive testing instrument designed to measure the compressive strength of concrete structures with enhanced accuracyand efficiency, Utilizing state-of-the-art electronic sensors and microprocessor technology, itdig itally records rebound values, eliminating manual reading errors associated with traditionalanalog models. Working Principle: The hammer’s spring-loaded mass impacts the concrete surface, and the rebound distance isautomatically measured by an integrated accelerometer. The rebound value (R) is instantlydisplayed on a back lit LCD screen and can be correlated to compressive strength using presetprogram calibration curves (e.g. ASTM C805, EN 12504-2 or IS 516). Key Features: Digital Precision: High-resolution sensor ensures repeatable results (+1 rebound value).Data Management: Stores up to 1,000 readings with timestamps; exports via USB/Bluetooth for report generation. User-Friendly: Large LCD display, ergonomic grip, and optional carbonation depth input for strength correction. Durability: lP65-rated housing for harsh job-site conditions. Applications: Ideal for quality control in bridges, buildings, dams, and pavements, Compatible with concrete grades from C10 to C100. Standards Compliance: Meets ISO 7500-1,BS EN 12504-2 and ACI 228.1R Advantages Over Analog Models: No manual recording errors. Real-time statistical analysis (mean, SD). Adjustable impact direction (horizontal/vertical). The digital rebound hammer streamlines field testing, reduces human error, and enhances traceability for engineers and inspectors.
