Universal laboratory IR Fourier spectrometer FSM 1202

The FSM 1202 universal laboratory IR Fourier spectrometer is designed for routine measurements and scientific research in the mid-infrared region of the spectrum.

The spectrometer is used for quantitative analysis and quality control of products in the chemical, petrochemical, fuel, pharmaceutical, food and perfume industries, for environmental control, forensic and other types of expertise.

The FSM 1202 spectrometer is based on a Michelson-type interferometer with self-compensation, which does not require dynamic alignment.

FT-IR spectrometer model FSM 1202 was produced by OOO Monitoring and OOO Infrapec (St. Petersburg) in the period from 1999 to 2016.
