Near infrared spectrometer SJNIR-R15
Product Introduction
The new near-infrared spectrometer SJNIR-R15 adopts internationally advanced micro electromechanical technology (MOMES) and embedded computer system to form a portable near-infrared spectroscopy analysis instrument. This instrument adopts a new spectral detection principle combining MOMES optical switch array and single point detector. The entire system has no movable parts and good spectral repeatability. At the same time, due to the use of single point detector, it has good model transfer characteristics among instruments of the same type.
