Continuity testing

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.
-
Pinhole Detector NOVOTEST ED-3D
The pinhole detector is designed for rapid non-destructive testing of coating continuity (e.g., film porosity) up to 500 μm thick by applying low voltage through a sponge soaked in a high-penetration liquid electrolyte to identify porosity and other discontinuities in protective dielectric coatings on metal products.

Digital Surface Profile Gauge NOVOTEST SP-1M
The digital surface profile gauge measures profiles on flat or curved surfaces and can also assess surface roughness (Rz) following abrasive blasting before painting.
-
Depth Gauge NOVOTEST LIMIT S-3
The mechanical depth gauge is designed to measure the peak-to-valley height of blast-cleaned surfaces, as well as the depth of focal corrosion, narrow holes, and grooves, depending on its configuration.
