Choosing the correct probe for your Elcometer High Voltage Holiday Detector

When it comes to testing the porosity of coatings using the high voltage or holiday detection method, regardless of whether you’re using a Continuous DC, or Pulsed DC detector, it’s important to choose the right probe for your application, so you can test thoroughly, efficiently, and ensure the most reliable results. Elcometer provides a wide range of probes and extension pieces to suit different applications and coating types. So, which probe should you choose? CONTENTS 0:41 - General probes - band brush, wire brush, conductive rubber 1:15 - Pipe inspection probes - circular wire brush, C-type wire brush, rolling spring probe 3:37 - Extension pieces and Second Hand Grip The band brush probe is supplied as standard with the Elcometer 236 and Elcometer 266 gauges, as it is ideal for most applications, and works especially well in small areas or on complex surfaces. The wire brush probes and conductive rubber probes are designed for larger surface areas, and are available in a range of different widths. The conductive rubber probe is also ideal for when testing on coatings that are more susceptible to scratches, and you want to avoid damaging the coating. The circular wire brush probes are perfect for internal pipe inspection, and the probe you select should be large enough for it tightly fit inside the pipe, leaving no gaps, ensuring you test all of the surface. You can also attach extension poles to the probe, which allow you to test deeper inside the pipe. The ‘C-Type’ wire brush is lightweight, easy to use, and ideal for testing the outside of pipes that have obstructions on them, such as valves or inspection hatches. Alternatively the rolling spring probe is tightly wrapped around the pipe and simply rolls along as you move, allowing you to quickly and reliably test long sections of pipe. The rolling spring is available in either phosphor bronze or stainless steel; and while both work in the same way there are advantages depending on which one you choose. There are a range of probe extension pieces which can be attached to any of Elcometer’s high voltage holiday detectors, to make it easier testing floors or large structures, or to test deeper inside pipelines. The Elcometer 236 also has its own telescopic probe handles, which can extend up to 3.6m (142”) in length, for easy access to difficult areas. There’s also a second hand grip for the Elcometer 266, designed for two handed use without compromising its safety, which is ideal for testing pipes and tank floors. WORKING SAFELY - While this video is intended as a guide, you should always consult the operation instruction book of high voltage equipment before use, and always take extreme care when using high voltage equipment.
