Yokogawa Electric Corporation is a globally renowned Japanese industrial automation and control company, founded in 1915 and headquartered in Tokyo. It specializes in measurement, control, and information technologies, providing high-precision instruments and solutions for industries such as oil and gas, chemicals, power, pharmaceuticals, and water treatment. Yokogawa pioneered the world’s first distributed control system (DCS), CENTUM, in 1975, which revolutionized process automation in large-scale industrial facilities. The company’s product portfolio includes pressure transmitters, flow meters, analyzers, recorders, and advanced IoT-enabled systems for digital transformation. With a presence in over 60 countries and a workforce of approximately 17,000 employees, Yokogawa combines technological innovation with a commitment to sustainability, helping customers achieve operational efficiency, safety, and environmental goals.
The Yokogawa FLXA21 is a versatile 2-wire, dual-channel liquid analyzer designed for comprehensive process monitoring in industrial applications. Part of Yokogawa's OpreX Analyzers family, this modular analyzer supports multiple measurement parameters including pH/ORP, conductivity, inductive conductivity, and dissolved oxygen. Its dual-channel capability allows for redundant measurements or simultaneous monitoring of two different parameters, providing exceptional flexibility and reliability for process control systems.
