INTRODUCTION

MEWOI-P78U online Porosity Holiday Detector is a special testing equipment used to detect oil and gas pipelines, cables, enamel, metal tank, hull and other protective coatings flaws. It is a professional and practical equipment.

PRINCIPLE

The detector generates a high DC voltage that is applied to the coating surface through a probe. The detector is connected to the substrate via the high voltage returned. When the probe is passed over a coating flaw, then the electrical circuit is completed and current flows from the probe to the substrate. As a result, audible and visual alarms are activated in the detector and a spark may be produced at the flaw.

FEATURES

1,microelectronic integrated high voltage generator, to overcome static phenomenon;
2,digital display, improve the accuracy of the output;
3,high voltage and power supply voltage automatic switching;
4,POST function;
5,anti-static, high pressure mistyped protection
