"UAN lab NIR instrumentation" likely refers to a type of Near-Infrared (NIR) instrumentation used in a laboratory setting. NIR spectroscopy is a technique that utilizes the near-infrared region of the electromagnetic spectrum to analyze the composition of materials. In this context, it seems to be used for analyzing urea solution, DEF (Diesel Exhaust Fluid), and UAN (Urea-Ammonium Nitrate) solutions.
