Overview
The ZD-310 and ZD-31 Integrated Rebar Locators are professional-grade instruments designed for detecting the position of internal reinforcement, measuring concrete cover depth, estimating rebar diameter, and identifying rebar spacing. Compact, accurate, and user-friendly, these devices are essential for construction quality control, structural assessment, and civil engineering applications.
Key Functions
Detects the location and orientation of reinforcing bars
Measures protective layer thickness (concrete cover depth)
Estimates rebar diameter and spacing
Supports multi-mode scanning: grid, profile, waveform, and thickness modes
Provides wave scan and JGJ detection capabilities
Features USB connectivity for data upload and analysis
Compact design with backlit display for clear data viewing in all environments
