Fiber Optic ATR Probes
Near & Mid IR-fiber ATR Probes can be used in any type of FT-NIR, FT-IR, and other IR-spectrometers, photometers and IR-LED or QCL spectral sensors. ATR immersion fiber optic probes are suitable for reaction monitoring in a lab, pilot plant and for fully automated process control.
Key Features
● High throughput in any part of near and mid infrared-spectrum
● ATR tip shaped for immersion in the liquid flow without dead zone
● Flexible and robust for industrial applications in harsh environment
● Compatible with all spectrometers and automated process-interfaces
