Sika Dr. Siebert & Kühn

Sika Dr. Siebert & Kühn GmbH & Co. KG, commonly known as SIKA, is a German manufacturer of measurement and calibration instruments for industry, headquartered in Kaufungen near Kassel. The company was founded in 1901 by Carl Siebert and Albert Kühn as Dr. Siebert & Kühn, a factory for chemical and physical precision instruments, primarily precision thermometers and technical glass apparatus. The name SIKA is derived from the initial letters of the founder's name Siebert and the founding location Kassel. Still family-owned and now led by the third and fourth generations of the Siebert family, SIKA has grown over more than 125 years into an internationally active specialist in temperature, pressure and flow measurement. SIKA is best known as the inventor of the machine thermometer. In the 1930s Hans Siebert developed the prototype for the industrial thermometer, which spread worldwide across industry and shipping and was standardized by 1962 with significant involvement of the company owner. In 1939 the company received a patent for a machine thermometer, and further machine thermometers were later registered as utility models. Over the decades SIKA expanded its portfolio to include flow monitoring devices, level monitoring devices, electronic measurement programs, and calibration technology. Today its products are divided into three main groups: mechanical measurement technology (machine and dial thermometers, thermowells, manometers, force and weight measurement technology), flow measurement technology (flow switches, level monitors, flow meters), and electronic measurement and calibration technology (calibrators, controllers and display instruments, handheld measuring instruments, temperature and pressure sensors). SIKA's sensors and calibration devices are found in the products or production processes of companies across many industries, including heating, ventilation and air conditioning technology, shipbuilding, automotive and commercial vehicle construction, and industrial technology. The company has a long export tradition and established international subsidiaries, including Sika France S.A.R.L. (1963), Sika Systemtechnik GmbH (1994) and Sika USA Inc. (2004), while also expanding sales activities in China. Its marine products were certified in 1971. SIKA continues to develop digital solutions such as the Digital Calibration Certificate for TP Premium, and serves growth areas such as data center liquid cooling and heat pumps. The company remains a private, family-owned German Mittelstand business with a global reach.

Sika Dr. Siebert & Kühn was founded in 1901 by Carl Siebert together with Albert Kühn as Dr. Siebert & Kühn, a factory for chemical and physical precision instruments, mainly precision thermometers and technical glass apparatus. The company name SIKA is derived from the initial letters of the founder's name Siebert and the founding location Kassel. In 1933 Hans Siebert, son of Carl Siebert, took over as sole owner and head of the company. In 1934 Albert Kühn sold his shares to Carl Siebert. During the 1930s Hans Siebert developed the prototype for the industrial thermometer, which spread worldwide across industry and shipping and was standardized by 1962 with significant involvement of the company owner. In 1939 the company received a patent for a machine thermometer; further machine thermometers were later registered as utility models. In 1963 a branch was established in France, Sika France S.A.R.L. In 1969/71 the factory and office buildings in Oberkaufungen were expanded. During this time flow monitoring devices were developed, followed somewhat later by level monitoring devices. In 1971 SIKA's marine products were certified. Werner Siebert, son of Hans Siebert, joined the company in 1973 as managing partner. In 1976 the development of a marketable electronics program followed. In 1994 Sika Systemtechnik GmbH was founded, and in 2004 Sika USA Inc. was established, while at the same time the expansion of sales activities in China was pursued. With Christian Siebert, grandson of the founder, and Sebastian Siebert, the third and fourth family generations now share the leadership of the company. Today SIKA is a manufacturer of measurement and calibration instruments for industry, headquartered in Kaufungen near Kassel. The company develops products for temperature, pressure and flow measurement. Its products are divided into three groups: mechanical measurement technology (machine and dial thermometers, thermowells, manometers, force and weight measurement technology), flow measurement technology (flow switches, level monitors, flow meters), and electronic measurement and calibration technology (calibrators, controllers and display instruments, handheld measuring instruments, temperature and pressure sensors). SIKA is the inventor of the machine thermometer and has developed devices for flow measurement and temperature calibration. Its sensors and calibration devices are found in the products or production of companies in various industries such as heating, ventilation and air conditioning technology, shipbuilding, automotive and commercial vehicle construction, and industrial technology.
