Ultrasonic Rebound Hammer – Atomfair-URH-639

Product Overview

The Atomfair-URH-639 Ultrasonic Rebound Hammer is a professional non-destructive testing instrument designed for measuring the compressive strength of concrete. It integrates two testing methods: rebound method and ultrasonic-rebound combined method, offering high efficiency, accuracy, and ease of use for on-site testing scenarios. Compliant with international standards, this instrument is widely applicable in construction quality inspection, maintenance of existing structures, and other related fields.

Compliance Standards

Rebound Testing: International Standard “Technical Specification for Testing Concrete Compressive Strength with Rebound Hammer”
Ultrasonic-Rebound Combined Testing: International Standard “Technical Specification for Testing Concrete Strength with Ultrasonic-Rebound Combined Method”

Key Features

Dual Testing Modes: Supports both rebound method and ultrasonic-rebound combined method, realizing integrated testing with one device. It can measure rebound value, sound time, and sound velocity simultaneously, simplifying operation procedures.
Instant On-site Results: After testing, the instrument directly analyzes and generates results of both rebound method and ultrasonic-rebound combined method, eliminating the need for additional waiting time.
Test Date Setting: All test data are saved with corresponding date information, facilitating user’s data classification, management, and traceability.
High-Speed USB Data Transmission: Equipped with genuine USB data transfer function, enabling fast transmission of test data to computers for further in-depth analysis and processing.
Infrared Communication: Adopts infrared transmission technology between the ultrasonic module and the rebound hammer, eliminating the trouble of dragging signal cables and improving flexibility in on-site operations.
Professional Data Analysis Software: Comes with powerful professional Windows data analysis and processing software. Test results are presented intuitively in the form of graphics and images. It can directly generate Word test reports or import data into Excel, ensuring efficient and convenient data sorting and reporting.
