the halm philosophy in a nutshell: 
we create solutions!

halm – the story behind the name

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.

history

halm originally catered for several different sectors, including materials testing in the chemical, pharmaceutical and automotive industries, and also manufactured audio systems.

At the end of the 1990s, halm was one of the first German suppliers to enter the up-and-coming PV industry. With its IV tester for the production of solar cells and modules, the company soon captured a major share of the global market.

Today, halm can look back on more than 20 years of experience in PV measurement technology. The company is acknowledged internationally as a technology leader and one of the premium suppliers in this field.

All halm products are engineered and manufactured at the company's headquarters in Frankfurt, where about one-third of the employees are engaged in the development of state-of-the-art equipment and solutions.

strong products – strong support

For halm, excellent service is just as important as top-quality products. To achieve this, we have established a global support network that ensures a fast and constructive response. To assist our clients in implementing our products, we also offer purpose-built demo centers for cell and module measurement systems in Germany and China. Our integration partners include numerous renowned companies such as Applied Baccini, Folungwin, J&R, Maxwell and many more.
