DCVG Surveyor Holiday Detector

The DCVG Surveyor Holiday Detector is a sophisticated electronic Milli-voltmeter with a 20000 Mega-Ohm input resistance.

Product Overview

DCVG  Surveyor Holiday Detector

Model: EPT-4000

Typical Applications

Analog DCVG Holiday detector is able to detect very low voltage gradients and provide easy methods of finding any coat defect in a pipeline by using analog panel meter. Not only is DCVG Holiday Detector able to show the ON and OFF voltage gradient of a pipeline, but it's also able to show the difference between ON and OFF in interruption mode.

DCVG  Surveyor Holiday Detector

It is powerful and an accurate equipment for detecting and tracking the escaping currents of the pipelines.
