Rebar Locator

Rebar Locator (Rebar Scanner) Model LR-G150

The LR-G150 Rebar Locator (Rebar Scanner), manufactured by LANGRY (Singapore), is a non-destructive testing (NDT) laboratory and field inspection instrument designed for the evaluation of concrete structures. This device accurately detects the location, distribution, diameter, and concrete cover depth of reinforcing bars (rebars) within concrete elements.

By utilizing advanced sensor technologies and an ergonomic design, the LR-G150 enables fast, precise, and reliable testing, making it ideal for a wide range of construction, rehabilitation, quality control, and structural inspection projects.

Main Applications of the LR-G150 Rebar Scanner

• Detection of the position and distribution of rebars inside concrete structures

• Measurement of concrete cover depth

• Determination of rebar diameter and spacing

• Inspection and evaluation of the location and distribution of ferromagnetic or conductive materials in non-magnetic environments

• Suitable for construction, rehabilitation, maintenance, and quality control of concrete structures
