What the ZBL-R630A measures

The ZBL-R630A is an electromagnetic-induction rebar detector. As you scan, it locates reinforcing bars in concrete and reports their position, the concrete cover over them and an estimate of bar diameter, and it can build a rebar distribution map during testing. Two detection ranges cover cover depths from 3 mm to 196 mm, and two probes support large-area scanning as well as small or detailed areas.

It detects metal. Cables and metal pipes can also register, so a signal is a prompt to check, not a guarantee that it is a bar. It does not show voids, cracks, honeycombing or the quality or strength of the concrete itself: for those you need an ultrasonic instrument. The detector is direction-sensitive, with the strongest signal when the probe runs parallel to a bar, and the ZBL manual advises resetting about every ten minutes during use.

Is it the right instrument?

Good fit for

  • Locating bars before core drilling, cutting, chasing or fixing into reinforced concrete.
  • Checking concrete cover against design or durability requirements.
  • Estimating bar diameter and mapping reinforcement layout without breaking out the concrete.
  • Surveyors and contractors who need a first-pass survey before a more detailed investigation.

Not the right tool for

  • Assessing concrete quality, uniformity or strength. Use a pulse velocity tester such as the A1410 PULSAR or UK1401 SURFER.
  • Imaging voids, cracks or delamination. See the A1040 MIRA range.
  • Finding bars at depths beyond the stated 196 mm cover range, or reading to the millimetre at the deepest range: stated accuracy widens with depth (±1 mm up to ±4 mm).
  • Replacing an engineer's judgement where cover compliance is contractual.

Frequently asked questions

What does the ZBL-R630A measure?

Reinforcement position, concrete cover over the bars, and an estimate of bar diameter, using electromagnetic induction. It can also build a rebar distribution map while you scan.

How deep can it detect rebar?

Cover is measurable from 3 mm to 196 mm using its second range, with the first range covering 3 to 98 mm. Stated accuracy is ±1 mm at shallow cover and widens to ±4 mm at the deepest part of each range.

Can it show voids, cracks or concrete strength?

No. It locates metal. For concrete quality use an ultrasonic pulse velocity tester such as the A1410 PULSAR or UK1401 SURFER; for imaging see the A1040 MIRA 3D PRO. The rebar scanner vs ultrasonic tester guide explains the difference.

Will it detect things other than rebar?

It responds to magnetic and conductive objects, so cables and metal pipes can register. Treat a signal as a prompt to check.

How much does the ZBL-R630A cost in Nigeria, and how long does delivery take?

The price depends on your location and what is supplied with the unit, so we quote each order. Send your city and country and we reply with a formal quotation covering price, delivery terms and lead time. Nigeria and Ghana are quoted separately.

Do you hold the ZBL-R630A in stock?

No. We supply to order, and the quotation sets out the delivery arrangement.
