HC-GY31 Advanced Rebar Detector & Concrete Cover Meter
The HICHANCE HC-GY31 is an advanced rebar detector featuring a separate scanning probe for locating reinforcing steel, measuring concrete cover thickness, estimating rebar diameter and assessing reinforcement distribution. Designed for professional non-destructive testing, construction quality control and structural inspections.
Key Features
- Detection Depth: Dual measurement ranges of 1–105 mm and 5–205 mm.
- Concrete Cover Accuracy: ±1 mm from 6–80 mm, ±2 mm from 81–120 mm and ±4 mm from 121–205 mm.
- Rebar Diameter Estimation: Supports Ø6–50 mm reinforcing steel, with a maximum estimation error of ±1 diameter specification.
- Separate Scanning Probe: Four-wheel probe with positioning light guide for accurate rebar location.
- Advanced Scanning Modes: Supports profile/grid scanning, continuous scanning and automatic measurement storage.
- 5-inch Colour LCD: High-definition display for clear on-site measurement results.
- Bluetooth Connectivity: Built-in Bluetooth for compatible mobile app integration.
- High-Capacity Storage: Stores up to 2 million measurement points.
- Extended Battery Life: Rechargeable lithium battery providing over 21 hours of operation.
Accurate Rebar Detection & Cover Measurement
The HC-GY31 locates reinforcing steel and measures concrete cover thickness across two detection ranges, reaching a maximum depth of 205 mm. Its high-precision sensor and interference-resistant detection algorithm support reliable measurements in reinforced concrete structures, including areas with closely spaced reinforcement.
Separate Probe & Advanced Scanning
The four-wheel scanning probe incorporates a positioning light guide for accurate rebar identification. Profile/grid scanning and continuous scanning modes allow operators to assess reinforcement spacing, distribution and orientation efficiently during structural inspections.
Data Management & Reporting
The HC-GY31 features automatic data storage, Bluetooth connectivity and professional PC software for data analysis and inspection report generation. Its 5-inch colour display and high-capacity memory support efficient field measurements and documentation.
Typical Applications
- Rebar location and concrete cover thickness measurement
- Reinforcement spacing, orientation and distribution assessment
- Structural inspections of buildings, bridges and tunnels
- Construction quality assurance and acceptance testing
- Pre-drilling and concrete coring inspections
- Assessment and refurbishment of existing concrete structures
