Product Description
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
