The TRANSIC Extractive process gas analyzer system (PGA) combines the benefits of a transmitter design with the flexibility of an extractive analyzer system. TRANSIC Extractive is the ideal solution for monitoring O₂ concentrations in plants and processes across a wide range of industries. The system uses state-of-the-art laser spectroscopy to perform reliable measurements even in difficult conditions. As a modular system, it can be adapted to different industry standards and virtually every application, and can even be used in hazardous areas or hygienic areas without any problems.
