The Ideal Choice for Online Detection
The IAS-PAT SE online near-infrared spectroscopy analyzer is designed for industrial process analysis, enabling effortless and worry-free process control, real-time tracking of process changes, and ensuring low input and high returns through visualized data.

With a safety explosion-proof design, the IAS-PAT SE undergoes multiple pressure tests and can be equipped with a Type IIB/IIC explosion-proof enclosure as needed, reducing operators' exposure to hazardous chemicals and ensuring safe and stable production. The instrument's spot diameter can be configured during manufacturing based on application requirements, better aligning with your production needs. It supports various standard communication protocol interfaces, facilitating seamless integration into process systems and providing clear insights into data throughout the entire production cycle.
