These analyses have proven to be as accurate as traditional lab testing for liquids, powders, solids, slurries, pastes, emulsions and/or suspensions. Our systems deliver the real-time data out-put that has made LT Industries a recognized NIR leader in process measurement for control. The Quantum 1200 Process Analyzer Series combines analytical power and intelligence with ease of use in an integrated systems package. A pre-dispersed, monochromatic beam of light travels through the patented harmonic drive grating mechanism, where is it separated into discrete wavelengths and sent through a fibre optic link to illuminate the sample. The light transmitted back through the fibre optic link is converted into an electrical signal, which is compared by the microprocessor to the calibrated responses in memory. The data output results of this comparison are then used for process control Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment Delivery condition, FCA: Oradea/Romania We can deliver/export everywhere in the World.
