Test Equipment & Instrumentation, Hire, Sales & Technical Services Elcometer 236 DC Portable Holiday Detector Home   Elcometer 236 DC Portable Holiday Detector The Elcometer 236 uses a high voltage technique to locates flaws in insulating coatings on conductive substrates. A power supply generates a high DC voltage which is supplied to a suitable probe. As the probe is passed over the coated surface, a flaw is indicated by audible and visual alarms in the detector and probe handle. No damage should occur due to the low current capacity. The Elcometer 236 is ideal instrument to use when testing: Insulating coating on oil, gas and water pipelines made from metal or concrete. Bitumen or epoxy on concrete eg. storage tanks, water and sewage treatment facilities. Flexible membranes on concrete bridge decks Vitreous enamel on steel eg. chemical reactors or storage tanks High voltage testing of insulation The sensitivity can be adjusted to ignore stray current flow so that only the flaws are detected.
