The Guided Wave Model 412 process Analyzer offers remote multi-channel near-infrared (NIR) or visible (Vis) spectroscopic scanning and analysis. Essentially a smart chemical sensor, the Model 412 provides exceptional signal-to-noise, excellent wavelength stability, NIST traceable wavelength calibration, dual-beam optics and built-in diagnostics. Process operators, engineers, and researchers will appreciate the Model 412's ability to monitor up to 12 process streams (or points within a stream) with accuracy, repeatability, and reliability.
