Social responsibility

For production processes in our company, we have taken voluntary measures to reduce CO2 emissions. We only use renewable energies. Electricity that cannot be generated by our own solar plants is supplemented by regional green electricity. Heat pumps that run on renewable energy round off our contribution to the environment. People and nature are important to our family business.

The production in our factory in Ennepetal as well as the selection of regional suppliers secures jobs in Germany. Partial components of the products are assembled in a workshop for the disabled in Germany. Taking social responsibility also means using ecological resources responsibly. With this in mind, we have developed completely maintenance-free voltage testers through innovative and power-saving circuits.

Testing equipment for electrical engineering

All our products are “Made in Germany”. Due to the fully in-house manufacturing process, we can ensure a high level of quality and offer you customised special solutions. This includes the careful selection of high-quality materials and the comprehensive testing of each individual unit.
