Radar Quantum Mini Dual-Frequency Concrete Scanner
The Quantum Mini Concrete is a handheld all in one ground penetrating radar (GPR) concrete scanner from US Radar billed as the world first dual frequency concrete scanner. It removes the usual dilemma of choosing between a deeper lower frequency antenna and a sharper higher frequency one by putting a 1000 MHz and a 2000 MHz antenna in one compact unit. It is used to scan floors, walls, and ceilings for rebar conduits, post tension cables utilities, and voids before coring, cutting, or drilling. It is sold under the Humboldt name as the HC-2975 Quantum Mini Concrete Scanner and by other distributors.
Key Features Quantum Mini Concrete
- Dual-frequency radar: a 1000 MHz antenna for deeper scans and a 2000 MHz antenna for very high resolution of shallow targets so there is no need to swap antennas or repeat a scan
- Flexible scanning: scan with both or either frequency with both datasets shown at the same time
- Great depth range: distributors quote scanning almost 2 m below the surface and Humboldt datasheet shows ranges of roughly 0.46 m for the 2000 MHz channel to 0.91 m or more for the 1000 MHz channel in typical concrete
- Handheld, all-in-one design: a compact, rugged wireless unit for scanning floors, walls, and ceilings
- 10-inch LCD screen: real time viewing and on-board 3D processing with a selection of color palettes and horizontal slicing for deeper data analysis
- Radar controller computer: a multi core Intel Atom processor and a 32 GB solid state drive according to Humboldt
- Reporting and mapping tools: report generation plus Google Earth and satellite imaging integration
- Software compatibility: works with a variety of third party processing packages
- Standards: Humboldt lists ASTM C803 and BS 1881 for the HC-2975 listing
- Simple operation: designed so users don’t need to choose antennas in advance or find out afterwards that a different antenna was needed
Typical Applications
- Locating rebar, conduit, and post tension cables before coring or cutting
- Concrete slab, wall, and ceiling scanning
- Bridge deck and structural inspection
- Detecting voids, utilities, and other anomalies in and beneath concrete
- Contractors, concrete cutters, and engineers who want one tool for all scanning
Why Choose It
Having both depth and resolution in one pass saves time and avoids missed targets. For anyone who scans concrete before drilling or sawing, the Quantum Mini Concrete offers a lighter simpler alternative to switching antennas.
