Metrel

Metrel is a Slovenian manufacturer specializing in portable electrical test and measurement instruments. Founded in the mid-20th century, the company designs instruments used for verification, safety testing, and diagnostics in power generation, construction, manufacturing, and service industries. Metrel’s portfolio spans handheld testers, multifunction analyzers, and software solutions deployed by utilities, contractors, and certification bodies.

History

Metrel traces its roots to post-World War II industrial initiatives in Ljubljana, evolving through decades of product development and export expansion. Early milestones include the introduction of insulation testers and earth resistance meters that served regional utilities and industrial plants, followed by a transition into digital technologies in the 1980s and 1990s. Strategic growth involved participation in trade exhibitions alongside companies such as Siemens, ABB, Schneider Electric, and General Electric, and collaboration with research institutions like the Jožef Stefan Institute and universities in Ljubljana and Graz. During the European integration era, Metrel adapted to regulatory frameworks influenced by the European Union directives and standards-setting organizations including International Electrotechnical Commission and CENELEC. Expansion of export markets led the company to engage with distributors and partners across Germany, France, United Kingdom, Italy, United States, Australia, and China.
