For OHE, quality assurance is the be-all and end-all. All our products are checked according to a multi-level quality inspection system specified in DIN EN ISO 9001. None of our products leaves our production facilities in Hattingen without having passed the complete final inspection cycle. Innovative, high-tech testing equipment forms the central element of our quality assurance systems. In addition to common measuring instruments, we also use special testing equipment and software.
