INTRODUCTION

MEWOI-TL78 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.

APPLICATIONS

1,oil and gas Anticorrosive factory, pipelining company, construction departments and qualitative inspect branch. 
2,also use to gas company and water company pipeline inspecting 
3,Shipbuilding, petrochemical plant, factory, machinery plant, enamel factory and bridge engineering anticorrosion-layer inspecting.
4,Pipeline transportation company anticorrosion-layer inspecting

FEATURES

1,Low power consumption, small size, light weight。
2,Microelectronic integrated high voltage generator,to overcome the electrostatic;
3,digital display,high-precision;
4,Automatic exchange for High voltage and source voltage;
5,intelligent charging;
6,Adopt imported microswitch, action is sensitive and reliable and with good stability;
