NJR51+ Rebar Location System

Purpose

NJR51+ rebar Location system is used to test rebar diameter, distribution, coating thickness in concrete.

Specification

JGJ/T152-2008

Performance Longer service life of the Connector Clip: The instrument has long service life because of using Lemo Connector Clip which comes from Swiss and uses for aircraft industry.

Good quality of signal cable: The signal cable has long service life because of its flexible and substance.

High precision and stability: The instrument can locate the steel-bar accurately and quickly.

Longer service life of the sensor: Improve the service life by paste abrasion resistance allowance bottom of the sensor

Single sensor: No-change sensor in test, switching between high and low test range can assure the precision of test data and the test depth.

Display test information real-time: Display the test data directly to avoid man-made errors.

Grid and section scan mode: Instrument can display steel b .

Three-wheel steel-bar scan system: The system can assure scan path along line and the precision of test data.

Powerful Windows data process and analysis software: Software can display analysis result by diagram. Test data can be export to word or Excel easily.
