SXZD31

Product Overview

The SXZD31 series integrated rebar scanner is mainly used for testing the position of rebars, cover thickness, rebar spacing, and rebar diameter within concrete structures, and can accurately draw the distribution map of the entire rebar, providing high-precision detection data quickly. The main unit and sensor are integrated, making it convenient and quick to carry and operate on-site. It adopts a multi-coil structure design, which is faster, more accurate, and has stronger resolution.

Functional Characteristics:
Thickness Measurement: Intuitive and precise, accurately displaying the position, spacing, and cover thickness of rebars on the same screen;
Waveform Scanning: Displays the position, cover thickness, and rebar spacing of rebars through waveform peaks;
Grid Scanning: Displays rebar spacing and cover thickness in a grid pattern in both longitudinal and transverse directions, allowing for arbitrary switching between X-axis and Y-axis (i.e., horizontal and vertical coordinate directions) during testing;
Profile Scanning: Displays the position, cover thickness, and rebar spacing of measured rebars in a profile form;
JGJ Mode: Achieves 1-6 repeated measurements of a single rebar, automatically calculating the average value;
The first four modes fully support arbitrary flipping forward and backward, viewing data and graphics, and deleting erroneous test data at any time during the measurement process, facilitating on-site testing.

Ⅴ.Features and Functions:
- Thickness Measurement: Intuitive and accurate, precisely displaying the position, spacing, and cover thickness of rebars on the same screen;

- Waveform Scanning: Displays the position, cover thickness, and spacing of rebars through waveform peaks;

- Grid Scanning: Displays the spacing and cover of rebars in a grid pattern, both vertically and horizontally. During testing, it allows for arbitrary switching between X-axis and Y-axis (i.e., longitudinal and transverse coordinate directions) tests;

- Cross-sectional Scanning: Displays the position, cover thickness, and spacing of rebars through cross-sectional diagrams;

- JGJ Mode: Enables retesting of individual rebars 1 to 6 times, automatically calculating the average value;

The first four modes fully support arbitrary flipping through pages before and after during measurement, viewing data and graphics, and deleting erroneous test data at any time, facilitating field testin
