DETECTOR OF COATING DEFECT

DDRC 3 (Direct Current Voltage Gradient technique - DCVG)

The DDRC 3 is the latest generation of coating defect detector.

It makes it possible to search for pipelining defects using the DCVG technique

(Direct Current Voltage Gradient)

ADVANTAGES OF DDRC 3

 

Thanks to its electronic processing, the DDRC 3 is 10 times more sensitive than other DCVG equipments.

 

  • Detect defects earlier and operate through resistive soil (dry or porous asphalt) with an accuracy of 10cm.

  • Perfectly filtered (no influence of stray currents and alternative currents 50/60 Hz).

  • Self-adjusting system (patented)=no need to adjust the off-set manually.

  • Possibility of using sticks without electrodes.
