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.

● 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
