Around 14.5 percent of Anton Paar GmbH's annual turnover is invested in research and development each year.

• Anton Paar GmbH develops, produces and distributes high-precision laboratory instruments and process measuring systems, as well as customized automation and robotics solutions. The company is a market leader in the fields of density and concentration measurement as well as rheometry and the determination of dissolved CO₂.^[5] In addition to the location in Graz (Austria), Anton Paar GmbH has other production subsidiaries: Anton Paar TriTec (formerly CSM Instruments) in Peseux (Switzerland),^[6] Anton Paar ProveTec GmbH (formerly Petrotest Group) in Dahlewitz (Germany),^[7] Anton Paar OptoTec GmbH (formerly Dr. Wolfgang Kernchen) in Seelze/Hanover (Germany),^[8] AXO Dresden (Germany),^[9] Anton Paar TorqueTec (formerly Brabender) in Duisburg (Germany) and Hackensack (USA)^[10] as well as Anton Paar QuantaTec (formerly Quantachrome Instruments) in Boynton Beach (USA).^[11] Anton Paar GmbH has 37 sales subsidiaries worldwide as well as numerous international sales partners.^[12]
• Anton Paar ShapeTec GmbH offers customer-specific solutions in sheet metal and joining technology, the machining of complex parts with low tolerances, the production of flat electronic assemblies and the assembly of mechatronic system assemblies. The main site of Anton Paar ShapeTec GmbH is located in Wundschuh (Austria). There are further production sites in Wolfsberg (Austria),^[13] Sijekovac/Brod (Bosnia) and Zalaegerszeg (Hungary).^[14]
• Anton Paar SportsTec GmbH in Wundschuh (Austria) manufactures systems such as soccer simulators (skills.lab Arena and skills.lab Cube). High-precision ball machines, cinema beamers, laser sensors and high-speed cameras are used to help footballers improve their performance. The skills.lab Studio is a system from SportsTec that can be used specifically to train cognitive skills, even in areas outside of sport.
• 24 Asset Management GmbH was founded in 2010 and buys, develops and lets real estate in the greater Graz area (Austria).^[15]
• In March 2018, the Sudhaus (Anton Paar Sudhaus GmbH), a two-toque restaurant with a show brewery, opened on the premises of Anton Paar GmbH in Graz (Austria).
• Founded in 2021, Anton Paar ConsumerTec GmbH in Graz (Austria) develops and sells measuring devices and software products for the B2C sector.^[16]

The company was founded in 1922 by master machinist Anton Paar as a one-man repair workshop. He built up a good reputation and made his first contacts with universities and research institutes. He trained his daughter, Margareta Platzer, as a skilled worker in the 1920s. She followed in her father's footsteps as the first female master machinist in Styria in 1932. Her talent in precision mechanics and precision manufacturing, together with Otto Kratky's knowledge, formed the basis for the first scientific analytical instrument manufactured by Anton Paar: the Kratky small-angle X-ray camera, which was produced on behalf of Kratky.^[17][18]

In 1963, Platzer's son-in-law Ulrich Santner (1932-2020) took over the management of the company. He laid the foundations for the later expansion of the company in the field of measurement technology. He also intensified the exchange and contact with universities and contributed to the transfer of new technologies from research to industry.^[19]

In 1997, his son-in-law Friedrich Santner joined the management. He has been the sole CEO since 2002. The main focus of his work was the organization of worldwide sales via the company's own subsidiaries. Under his leadership, new sales and service branches were established and complementary measurement technology companies were acquired.^[20]

In 2003, the family business was incorporated into a charitable foundation.^[21]

In January 2020, Friedrich Santner's sons joined the management. Jakob Santner became CTO and Dominik Santner COO of the company, while Friedrich Santner remained CEO.^[22]

In 2023, the company opened a new technology center at its headquarters in Graz, which provides 1,000 workplaces.^[23]
