FTIR 4300

Portable FTIR spectrometer for non-destructive material testing on-site

The FTIR 4300 is a modern and portable spectrometer. It combines robustness and outstanding ergonomics with low weight and very good analysis properties. The device has a weight of only about 2 kg and is ideal for the flexible use out of the lab. In addition, the powerful optics enables measurements of demanding samples. Different interfaces (Diffuse Reflectance, External Reflectance, Grazing Angle, Diamond ATR, Ge ATR) allow an easy change between different sample types like IR-absorbing and IR-scattering samples, reflective metal surfaces with coatings or powders, pellets, granules, soils and minerals. The easy handling and user-friendly MicroLab software guarantee trusted results for experts as well as for newbies.
