The Universal Analyzers Model 1221 Series distillation sample probes are manufactured for demanding on-line gas analysis applications. The Model 1221 Solution has been designed to resolve key issues surrounding plant performance by improving measurement accuracy and reliability. The 316SS separator is self-cleaning, and designed to knock-out liquids and any heavy hydrocarbons present and wash them back into the process stream along with any solid deposits, eliminating the everyday issue of plugging conventionally seen with sample conditioning systems.
