Antstone Concrete Rebound Hammer Tester Schmidt 10-60MPa Portable

Description

Product Overview

The Antstone Concrete Rebound Hammer Tester is engineered for professionals who demand precision, durability, and ease of use in the field. Constructed from high‑grade stainless‑steel, the outer shell resists corrosion and impact, ensuring a long service life even in harsh construction environments. The internal spring mechanism, calibrated to international standards, delivers consistent rebound readings that correlate directly to concrete compressive strength ranging from 10 to 60 MPa. Weighing just 1 kg, the device balances robustness with portability, allowing technicians to carry it effortlessly in the included shock‑absorbing case.

Key specifications include a hand‑powered operation that eliminates the need for batteries or external power sources, a built‑in grindstone for surface preparation, and a set of interchangeable bounce and buffer springs that adapt to varying concrete densities. The device complies with ISO/DIS 8045, EN 12 504‑2, ASTM C 805, DIN 1048‑2, NFP 18‑417, JGJ/T 23‑2001, and other regional standards, guaranteeing that test results are recognized worldwide.

Usage

Designed for on‑site applications, the Antstone rebound hammer excels in a variety of construction scenarios. Whether you are assessing the structural integrity of a newly poured slab, verifying the strength of existing bridge decks, or conducting quality control on road pavement, the tester provides rapid, non‑destructive results. Its lightweight design enables single‑hand operation, while the ergonomic grip reduces user fatigue during extended testing sessions.

Before each measurement, the built‑in grindstone prepares the concrete surface, removing loose particles and ensuring a flat testing area. The technician then positions the hammer perpendicular to the surface, activates the spring, and reads the rebound value on the calibrated scale. The device’s clear markings and tactile feedback make it suitable for use in bright sunlight, low‑light conditions, or even dusty environments, thanks to its sealed internal components.

Because the tester does not rely on electricity, it is ideal for remote locations, temporary job sites, and regions with limited power infrastructure. The included portable case, featuring a shock‑proof sponge lining, protects the instrument during transport and storage, reducing the risk of damage from drops or vibration.

FAQ

What types of concrete can the tester evaluate?

The rebound hammer is designed for all types of reinforced and plain concrete used in walls, slabs, bridges, and road pavements. It is not suitable for ceramic tiles, brick, or other non‑concrete masonry materials.

How often should the device be calibrated?

For most field applications, calibration is recommended annually or after any significant impact or drop. Calibration kits are available from authorized Antstone distributors.

Can the rebound hammer be used in extreme temperatures?

Yes, the stainless‑steel housing and internal spring are rated for operation from -20 °C to +50 °C. However, extreme cold may affect spring elasticity, so allow the device to acclimate before testing.

Is the device compatible with other Schmidt hammer accessories?

The Antstone model follows the same dimensions and mounting points as standard Schmidt hammers, allowing you to interchange accessories such as additional springs or specialized heads.

What warranty does Antstone provide?

All Antstone Concrete Rebound Hammers come with a two‑year limited warranty covering manufacturing defects, along with access to technical support and calibration services.
