Since its founding in 1989, Spectrum Instrumentation has grown from a small development team into a globally recognized manufacturer of PC-based high-performance measurement technology. Founder and CEO Gisela Hassler has led the company for 36 years and is now bringing about the next milestone in the company’s history: To accommodate the company’s steady growth, a state-of-the-art headquarters is being built at the technology industrial park in Ahrensburg near Hamburg, Germany. The foundation stone was laid on September 9, 2025.
The management of Spectrum Instrumentation: founder Gisela Hassler (CEO), on the right Oliver Rovini (CTO) and Carsten Gralla (MD).
Founder Gisela Hassler recalls: “Our initial focus was on customized solutions, but as early as 1991, we developed and produced our first PC card. This product for digitizing electronic signals was a success and remained on the market for 17 years – an early sign of the longevity and customer-oriented service that characterizes the company to this day.” Gisela Hassler (CEO) leads the company together with Chief Engineer Oliver Rovini (CTO), who joined the company in 1995, and Carsten Gralla (MD), who has been part of the management since 2021.
In the year 2000, the development team implemented a modular concept: using different base cards combined with many plug-on modules, an enormous range of over 200 models was created for digitizing and generating electronic signals. The result is a unique product range in the industry. Later, the company developed the stand-alone measuring instruments of the NETBOX series, controllable from any PC, which are another international success story.

Today, customers include leading corporations like Intel, Siemens, Mitsubishi, Philips, and Bosch, as well as prestigious universities all around the world. Spectrum’s measuring instruments are used in aerospace and quantum research, materials science, medical and energy technology, automotive and aircraft construction, laser and fiber-optic based equipment, as well as communications and semiconductor automated testing systems. Applications are as diverse as research into dolphin communication and volcano early-warning systems. 140 Spectrum PC boards control the world’s largest particle accelerator at CERN.
Spectrum’s product range includes more than 200 instruments in several form factors
Spectrum stands for highest quality, a five-year warranty, and fast support directly from the hardware and software developers. Spare parts and services are available for 15 to 20 years – a rarity in the fast-moving electronics industry.
The new company building will provide Spectrum Instrumentation with the opportunity to continue its steady growth. All company departments, including research and development, production, sales, and administration, will have spacious, ultra-modern facilities. The building design incorporates high-tech infrastructure with collaborative spaces and quiet areas. The aim is to achieve a workspace that delivers flexibility, convenience, comfort, and productivity. The building is also positioned to allow further expansion whenever it is required. Many other innovative high-tech companies have already settled in this industrial area on the northeastern outskirts of Hamburg in northern Germany.
