The RAY-30 Infrared Oil Meter can be used to record either IR absorption or (with accessories) IR reflection spectra in the range of 4000 cm-1 to 400 cm-1 (wavelengths from 2.5 um to 25um). The user can do qualitative or quantitativeanalysis on the measured sample using either the stored spectrum or the plotted spectrum. It is a useful tool for petrology, the chemical industry, medical work, food,safety, the paper industry, environmental monitoring, the semiconductor industry, etc.,for material structure analysis.
