TQC Sheen high voltage pore detector Holiday Detector

The TQC Sheen High Voltage Holiday Detector or Porosity test enables the exact Detection of pores, defects, inclusions, thin spots and bubbles in a coating. The measuring device has been specially developed to revolutionise high-voltage DC testing of coatings and make it safer, simpler and more reliable than ever before.

High-voltage technology can be used to Coatings up to a thickness of 36 mm can be tested. This method is ideal for testing coatings on pipes, tank floors and other surfaces. Protective coatings. Also Coatings on concrete can be tested with this method.

The device has a number of unique features. One Current limitation to prevent damage to the coating, and a Safety handle without sensitive electronics. The extended ribbing of the handle forms an effective barrier between the high voltage and the user. The precise Sensitivity setting enables the Use on metal-containing or slightly damp coatings.
