Optek-Danulat GmbH- Optocouplers

Optek-Danulat GmbH, headquartered in Essen, Germany, has specialized for over 25 years in designing and manufacturing high-performance inline photometric analyzers for industrial liquid and gas processing. The company has grown into a global operation with major facilities in Germany, the United States, Singapore, and China, supported by a network of representatives in more than 25 countries. Optek’s core products are sensor-based process analyzers that measure turbidity, color, UV absorption, and dissolved oxygen under extreme temperature, pressure, and corrosive conditions. Key product families include the TF16-N series of turbidity sensors, the AF16-N single-channel absorption sensors, ColorSens inline color measurement systems, and the OXY-4 dissolved oxygen sensor. These sensor systems integrate advanced optoelectronics and robust mechanical design to deliver precise, real-time data directly in pipelines and vessels. Optek maintains large inventories in Europe and the US, enabling rapid configuration and delivery of analyzers tailored to specific customer requirements. The company serves demanding industries such as chemical, pharmaceutical, food & beverage, oil & gas, and water treatment, where inline monitoring is critical for quality and safety. Optek is recognized as a technology leader in process photometry, with thousands of installations worldwide and a strong patent portfolio in sensor design. Its unique dual-beam, sapphire-optical-window technology sets the standard for reliable, low-maintenance measurement in the most punishing process environments. By continuously investing in R&D and global service capabilities, Optek remains a trusted partner for engineers seeking accurate, durable inline analysis solutions.
