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.
