HV Potential Indicators

In the world of electrical testing, safety is paramount. The ISSWWW range of high voltage (HV) potential indicators and proving units are designed to ensure the safety of electrical installations by detecting the presence of high voltage. These indicators are crucial for safety, confirming that electrical systems are de-energised before maintenance. We stock quality brands, such as Seaward and Martindale, offering robust and reliable solutions, including portable options.
