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.
Key benefits and features of Pulse Holiday Detector NOVOTEST SPARK-1:
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.

VARIOUS ELECTRODES
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.
AUTOMATIC DEFECT SIGNALING MODE
The device has a sound alarm function when detecting an electric spark breakdown in the control process, which allows user to work with the device without permanent monitoring of the process, thus greatly simplifying the operator’s work.
