About us

Tradition for over 60 years

The company’s history takes us back to the company Brehmer Voltage Tester GmbH, which was acquired by the H+H Tools GmbH in 2009. The origins of the company lie in the production of glow lamps. In the 1950s, these were delivered to German switch manufacturers and tool manufacturers. To complete the range further, production was expanded in terms of single-pole voltage testers in the early 1960s. Since that time, we deal in detail with the manufacture and sale of single-pole voltage testers.


The outward design of the products has not changed much over the years. However, our ambition to further develop and improve the products has not ended. Through the implementation of new technologies, raw materials and manufacturing techniques, the products have been continuously further developed to meet the increasing product demands.


The quality and safety of our products are our top priority. For this reason, we produce our entire range at our site. An integrated examination of the products and the manufacturing process guarantee a high safety standard. Our production is also subjected to the monitoring by the VDE Testing and Certification Institute on a regular basis. Therefore, our customers can rely on high-quality and safe testing tools.
