Endress+Hauser (Endress and Hauser) is a Swiss-based globally operating process and laboratory instrumentation and automation supplier.

Its devices measure liquids and gases and are primarily utilized in the chemical industry as well as in the life sciences sector.

[21] Furthermore, in 2024, Endress+Hauser signed a strategic partnership in process automation with Sick AG, a sensor manufacturer based in Waldkirch, Germany.

Starting in 2025, Endress+Hauser will take over global sales of Sick's process analyzers and gas flow measurement devices.

[25] Additionally, Georg Endress founded the Biovalley network, which is a collaboration of biotechnology companies and universities in the tri-border area along the Upper Rhine.

[1][16][28] The products and technologies are primarily used by clients in the chemical, food and beverage, water and wastewater, oil and gas, life sciences, power and energy, mining, minerals, and metals industries.

[26][29][30] In the laboratory measurement technology sector, analytical instruments and bioanalytical systems are marketed under the Analytik Jena brand, serving science and research clients.

[34] Starting capital was a modest 2,000 Deutsche Mark; the first ‘operating facility’ was a room in Hauser's apartment in Lörrach, Germany.

The company broadened its offerings by incorporating new measurement principles and explored business opportunities in additional countries.

In 1977, Endress+Hauser Flowtec AG was founded at the headquarters in Reinach, serving as a development center for the flow measurement business area.

[31][44] At the beginning of the 2000s, production facilities in Germany and Switzerland were expanded, particularly at the locations in Reinach, Cernay, and Maulburg.

[55] Additional takeovers (Kaiser Optical Systems Inc., SensAction AG) strengthened the segment of process analysis and measurement of quality parameters.

[62] In 2018, shareholders of Analytik Jena AG sued over the stock price as compensation and demanded a higher cash settlement for the transfer of shares.

With his appointment as CEO, Altendorf announced the intention to further develop the field of laboratory and process analysis.

[68] In 2017, the group acquired Blue Ocean Nova AG, a manufacturer of inline spectrometers for monitoring quality-relevant process parameters.

[71] This included expansions of the headquarters in Reinach,[72] the production site in Maulburg,[73] as well as international locations in the United States and China.

Due to the diverse industries, segments, and countries served by the group, the impact of the pandemic was less severe than for other companies.

[9][75] At the turn of 2023/24, Klaus Endress stepped down from his active role in the company due to his age and resigned from the supervisory board but remained chairman of the family council.

Matthias Altendorf transitioned to the group's supervisory board and handed over management to Peter Selders, who had previously led the company's competence center for level and pressure measurement technology.
