NOVOTEST - Pulse Holiday Detector (SPARK-1)
Brand: Novotest
Model: NOVOTEST SPARK-1
Product Descriptions:
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 non-destructive 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 12mm and more, with a discontinuity size of 0.1mm.
- 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 aluminium 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 use in the temperature range from -40 to +50°C.
