HC-GY21 Concrete Rebar Nondestructive Tester

Description

Product Description:

Concrete rebar detectors are primarily used to determine the location, distribution, and orientation of reinforcing steel in concrete structures, as well as to measure cover thickness and rebar diameter. They are employed for quality inspection and acceptance of concrete structures during construction, and are also applied to rebar detection in bridges, tunnels, and other infrastructure. These devices facilitate assessments of the safety and durability of structures under construction, verify rebar quantities during the evaluation and reinforcement or retrofitting of existing structures, and detect the orientation and distribution of ferromagnetic and conductive materials within non‑magnetic media.

Features:

1. Displays the concrete cover thickness and rebar signal image in real time, and automatically locks the minimum value.

2. The upgraded sensor significantly enhances detection accuracy; the optimized signal-processing algorithm ensures data consistency and stability.

3. The built-in Bluetooth chip enables real-time on-site data upload via the Haichuang mobile app.

4. Featuring a compact design, it is equipped with a 5-inch HD full-color LCD display and a 32-bit CPU, delivering smoother core processing and more efficient detection.

5. Detachable high-capacity lithium battery with a low-power design; can operate continuously for over 28 hours on a full charge.

6. Supports JGJ testing functionality, meeting the requirements of relevant testing standards;

7. Supports remote software upgrades for the instrument, providing convenient service support; the PC driver is automatically compatible, eliminating the need for manual installation.

8. Professional data-processing software can easily generate test reports.
