YOKOGAWA NR800 Near Infrared Analyzer
The NR800 Near Infrared Analyzer achieves high-resolution, high S/N (signal-to-noise) ratio, and wide wavelength scanning range measurement with its newly developed interferometer and detector. The NR800 also offers exceptional stability, vibration resistance, and durability, inheriting features from earlier successful models. It includes improved usability features such as measurement channel and output configuration as well.
The NR800 allows online, real-time, continuous, multiple, and simultaneous measurement for properties and component concentration of various processes.
