From our base in Frankfurt, Germany, we design, build and ship PV measurement technology worldwide. We manufacture strictly in compliance with ISO9001 and ISO14001 standards. Our product portfolio ranges from advanced IV testers for the mass production of solar modules to solutions for the entire photovoltaic chain. All instruments are supplied with state-of-the-art halm software. Our in-house development ensures the seamless operation of the equipment and offers leading-edge data visualization, analysis, and monitoring.
In addition to well-known PV manufacturers, our clients include many testing institutes such as TÜV Rheinland, Fraunhofer ISE, TÜV Süd, CPVT, PV EL, ISFH, and CFV.
halm is owner-operated and looks back on more than 20 years of experience in the PV metrology field. Our unmatched technology combined with meticulous attention to detail, exceptional customer service and unlimited product upgradeability have made us the undisputed technology leader in our field.
Our company name is derived from the last names of our founders: H. Hellmann, H. Albert, A. Laux and A. Meixner. Four scientists who established the company in 1981 as an owner-run German technology company. Today the company is owned and run by brothers Moritz and Michael Meixner. Their strong affinity to Frankfurt ensures that R&D, sales and administration as well as in-house production will remain anchored in the Rhine-Main area in the future.
Before evolving into its current market specialization, halm was engaged in a multitude of other fields and sectors. As a result, the company looks back on a highly diversified and rich history of innovative solutions. This passion for tackling challenges and devising ingenious solutions still characterizes the company today and ensures that an unexpected solution to even the trickiest of cases can almost always be found!
