Introduction |
 |
This apparatus detects pinholes, vacuholes or flaws in coatings. The conductive background is earthed to instrument and a high voltage is applied by moving a brush across the coating. This value is a related to the coating dielectric strength. When a flaw is detected, then the current will spark through it whilst a light flashes and audible alarm sounds. For maximum safety a high impedance supply will collapse to zero upon detection.
