tanning lamp had become a popular consumer electronics item. After buying out AEG in 1973, a number of newly developed products were added to the range. Heraeus Noblelight now supplies infrared and ultraviolet emitters as well as UV-LEDs to a variety of industries, for use in automotive production, printing, plastics and semiconductors, analytical instruments, laser and environmental technology in solariums, and water and air treatment. Sensors Heraeus first started producing thermocouples and thermometers with platinum and platinum alloy wires under the directorship of Richard Küch. The technology still forms the basis of Heraeus temperature measurement technology today. By the mid-1960s, analysis technology was added to the product portfolio. After the takeover of the Belgian Electro-Nite Group in 1987, immersion thermocouples and gas probes were added to Heraeus's array of measurement technology for use in the steel and aluminium industry. In 1997, the company founded Heraeus Sensor-Nite, specialised in temperature sensors needed in platinum thin-film technology for use in automotive construction, electronics and household appliances. Customers Heraeus supplies products to manufacturing companies in the automotive sector, the aerospace sector, telecommunications, the chemical industry, medical technology and the steel industry.
