The InfraSpec NR801 EL is the at-line model of NR800 series FT-NIR analyzer. It employs exactly the same hardware in the heart of the system (interferometer and detector) as NR800 process model and thus realizing high S/N (signal-to-noise) ratio, high wave number resolution and wide wavenumber scanning range those done in the NR800 process model. Direct model transfer to/from the NR800 series including process model is another key feature. This model transfer capability will drastically cut down model implementation time and cost at project stage while it provides more flexible and efficient model upgrade during routine operation.Software specially developed for at-line model, SpectLand 2 at-line, will make operation simple and user-friendly and will improve the work efficiency for at-line and Lab. measurement application.
