Pulse Holiday Detector NOVOTEST SPARK-1

The pulse holiday detector detects defects such as thinning, microholes, and cracks in dielectric coatings on metals using the electrospark method, where a probe electrode scans the coating surface while the ground connector connects to the metal substrate; the electronic unit measures the voltage gaps between the electrode and the conductive base to identify defects.

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.

DESIGN

The electronic unit of the device is made of durable aluminum alloy, and dense rubber bumpers, which makes the device body resistant to falls and shocks, protect the side faces. Also, the device is not demanding on operating conditions, can be used in the temperature range from -40 to + 50 ° С.
