Introduction: ZBL-R630A is used to test the location of rebar in concrete, the thickness of the protective layer, and the diameter, orientation, and distribution of rebar by using an electromagnetic induction method. It also can be used to test the distribution of magnetic and conductor such as cables and metal pipes in non-magnetic medium and non-conducting medium Features: Unique all-wheel, dustproof and waterproof multi-parameter rebar probe ensures accuracy and reliability of data taking Rebar detection is automatically alerted by the probe via flashing red light The world’s first wireless onsite data transfer function, remote management also available Data can be stored on usb-thumb drive, great for field work The device can generate rebar distribution maps and rebar corrosion potential contour graphs Powerful professional analysis-process software allows for the automatic generation of test reports Specifications: Applicable range:Ф6mm～Ф50mm Protective layer thickness range (mm) First range:3～98 Second range:3～196 Maximum allowed error for protective layer thickness ±1(mm):3～79 ±2(mm):57～119 ±4(mm):70～196 Maximum Allowed Error for Diameters Measurement:±1 Common Type:√ Closely Bars Type:√ Transverse Section Bars:√ Grid Type:√ Signal Wave:× Scan Range:Boardless Data Correction:Manually Data Transfer:U disk Wireless Transfer:√ LCD:160×128 Power:Built-in battery Size:212×134×50mm Weight:0.9KG
