Non-Destructive Testing Instrument For Rebar Location And Rebar
Corrosion And Concrete Defect Testing
Application
After the building construction or bridges are finished, the
testing unit will test the structure every year to check whether it
has some defect inside and whether some potential influence by the
concrete. So the testing units will do some general testing work
and record it for future comparation, such as concrete coating
thickness testing, rebar location and distribution testing, rebar
corrosion testing, concrete crack width and depth testing, concrete
resistivity testing, concrete strength testing, and so on.

substance.
3. High precision and stability: The instrument can locate the
steel-bar accurately and quickly.
4. Longer service life of the sensor with high quality abrasion
resistance layer
5. Single sensor: no need to change sensor in test, just switch it
between high and low test range, so it can assure the precision of
test data and the test depth.
6. Display test information on real-time.
7. Grid and section scan mode: it can display steel bar
distribution and without concrete boundary limited.
8. Three-wheel steel-bar scan system can assure scan path along
line and the precision of test data.
9. Powerful Windows data process and analysis software can display
analysis result by diagram. Test data can be exported to word or
Excel easily.

SY-R61 Rebar corrosion tester
Parameters:
| Item | Name | Details |
| 1 | Test range | +/- 2000mV |
| 2 | Accuracy | +/- 1mV |
| 3 | Test point space | 1 ~99cm |
| 4 | Power | 6pcs No. 5 battery |
| 5 | Operating temperature | -4°C ~ +40°C |
| 6 | Humidity | < 90%RH |
| 7 | Environment | no Strong electromagnetic field |
Features:
1. Two test modes: The potentiometry and gradient method is used to
test steel-bar corrosion which suitable for different working
field.
2. Permanent reference electrode: Saturated CuSO4 solution is
sealed up completely in reference electrode. Field test keeps
clean, simple and pollution-free operations.
3. Automatic measure environmental temperature. Instrument is with
a environmental temperature module, it can measure, record and
display temperature quickly, no need thermometers.
4. Can save test date. Convenient for data management.
5. Display test result intuitively by icon mode, The icon color is
more dark, the steel-bar corrosion is more serious. User can
observe the corrosion degree intuitively.
6. USB transmission. Data can be transmitted to computer for future
process and analysis.
7. Powerful data process and analysis software, test data can be
exported to word or excel for future process and analysis.
