ZC3-E+ Digital Concrete Rebound Hammer (Color Touchscreen)

Description

Product Description:

This instrument is specifically designed for nondestructive testing of the compressive strength of concrete members in buildings, bridges, tunnels, and other structures. It features on-site sampling, automatic data recording, automated calculations, voice‑based result announcements, real-time display of strength values, seamless switching between measurement areas, and audible prompts upon completion of component testing. Additionally, it includes instrument management settings, online data uploading, and an optional Bluetooth printer for on‑site printing of rebound test results, significantly enhancing testing efficiency and reducing the workload of inspection personnel. In accordance with national and industry standards, it can be used to assess concrete strengths in the 10–60 MPa range; under applicable local standards, it is suitable for concrete strengths ranging from 10 to 80 MPa.

Product Features:

● Full-screen touchscreen interface

● Supports Chinese, English, numbers, special symbols, and pinyin input, making on-site editing more convenient.

● The six-axis gyroscope can automatically detect the impact angle.

● Employs a new high-precision, non-contact CMOS image recognition sensor.

● Supports core sampling technology for rebound testing, enabling rapid identification of the test area with the lowest rebound value.

● Automated temperature and humidity monitoring provides a clear, comprehensive view of the test environment.

● Real-time calculation of current magnitude value
