A pinhole detector is the ndt instruments used to detect pin hole,seal leak,cracks or flaw on the coatings.
PD-001 Pinhole Detector:
PD-001 Pinhole Detector is applied in the non-destructive detection and location of pinholes, bare spots or thin points in protective coatings applies for corrosion protection over metal and concrete (conductive) surfaces.
With corrosion an extremely costly and disruptive worldwide problem, preventative determination becomes essential.
For newly constructed tanks, pipelines and other installations, where corrosion prevention coatings have had to be applies, specifications will normally call for a specific coating to a specific thickness. By using our Detector to verify the competency of the sealing coatings, the contractor can be assures that his coatings responsibility has been met.

Pinhole detect machine:
Functions |
Detect the pinhole on the leveled straight plate with high speed. |
Detecting method: |
Ultraviolet tube |
Diameter of detectable pinhole |
10 μm |
Ultraviolet sensor |
Photoelectric Amplifier |
The minimum time interval of contiguous pinholes |
5 ms versus pinhole of 25 μm |
Maximum speed |
1830 m/min |
Marginal light shield |
6.3mm is a must:while the move ment range side of the plate or the width variation is within 1mm,the marginal light shield can be 3mm |
Maximum speed |
60mm/second |
Self calibration |
The maximum time interval is one week under general conditions; and more frequent self calibration must be conducted under worse conditions to ensure the normal operation of the system. |
