If you decide to buy a rebar detector, you may face all kinds of confusion. How to choose a rebar detector? You can consider it from its basic configuration and technical parameters. Reinforcement protective layer testers generally include probes, meters, and connecting wires. The meters can output analog or digital instructions. More advanced meters also have a graphic display function. Reinforcement detectors can be powered by batteries or external power sources.

1.The steel protective layer tester should pass the technical appraisal and must have a product certificate.

2.The protective layer measurement range of the rebar detector should be greater than 120mm.

3.The accuracy of the rebar detector should meet:

a. 0 ~ 60mm, ± 1mm.

b. 60 ~ 120mm, ± 3mm.

c. > 120mm, ± 10%

4.The range of applicable rebars up to now is Φ6 ~ Φ50, which is not less than 12 grades that meet the requirements of relevant steel bar diameter series.

5.The rebar detector shall have the function of measuring the diameter of the steel bar under the condition of unknown protective layer thickness.

6.The rebar detector should be suitable for environmental conditions where the temperature is 0 ~ 40 ° C, the relative humidity is ≤85%, and there is no strong magnetic field interference.

7.The rebar detector should be powered by DC when working, and the continuous normal working time is not less than 6h.

Before you buy the rebar detector, you must refer to the above points, and then make a careful comparison and analysis before making a decision. If you still have problems in this regard, please contact us and we will give you more professional advice! !!
