Polytec's PSS Spectrometers are available either in a tabletop housing or in a 19" rack-mount unit. They can be connected using fiber-optics to various measurement setups, for example immersion probes or flow cells. Furthermore, user-friendly software supports many NIR technology applications for industrial process control. The robust construction of the PSS systems works for production line applications, while delivering reliable, real-time data. Optical multiplexers offer the option to control several measurement points simultaneously from one spectrometer.
