Pulse Holiday Detector NOVOTEST SPARK-1
Pulse Holiday Detector NOVOTEST SPARK-1 is a device for detecting defects (thinning, microholes, cracks, etc.) in dielectric coatings on metals.
The principle of operation of the device is based on the electrospark method. A probe with electrode connected to one pole of the voltage source scans the surface of the tested object directly along the coating. The second pole of the voltage source from the ground connector is connected directly to the metal structure. The electronic unit fixes the gaps by voltage between the electrode and the conductive base.
RAPID TESTING OF COATING
Using the device is possible to do rapid nondestructive testing of the integrity of the coating of vessels (tanks, barrels, etc.), pipelines (inner and outer surfaces), ships and other structures with a coating thickness of up to 12 mm and more, with a discontinuity size of 0.1 mm.
Depending on the task, the device can be equipped with a T-shaped, sickle, brush, ring, spring and other types of electrodes for individual customer testing objects.
