The Model 1221 is a high-performance gas sampling probe designed for demanding online gas analysis applications. For full product specifications, refer to the Model 1221 sample probe page. It ensures continuous, representative sampling while preventing contamination from liquid and solid particulates. Because of its advanced self-cleaning mechanism, it reduces the risk of sample line clogging, improving system reliability and minimizing maintenance.
Built for precision, the Model 1221 features a robust 316 stainless steel separator that removes unwanted liquids and heavy hydrocarbons from the gas stream. Its self-cleaning design washes back collected materials into the process, maintaining consistent sampling conditions. Adjustable outlet temperature helps preserve sample integrity across a wide range of analytical measurements.
For modular sampling configurations and close-coupled analyzer installations, solutions such as the NeSSI Probe can be used alongside the Model 1221 to improve system flexibility and integration.
The Model 1221 is well-suited for applications including FCCU units, syngas production, pyrolysis gas, and ethylene and naphtha cracking furnaces. Its ability to handle varying gas compositions makes it a reliable choice for refineries and petrochemical plants.
For applications requiring efficient sample routing to multiple analyzers, the Sample Distribution Panel (SDP-1) can help streamline system integration and improve overall sampling efficiency.
Clean, representative samples are critical for accurate gas analysis. The Model 1221 prevents contamination at the extraction point, improving measurement accuracy and reducing analyzer downtime.
For applications requiring validation or manual sampling alongside continuous systems, the Grab Sampling System can provide a complementary solution for accurate sample collection.
Designed for durability, the Model 1221 minimizes maintenance through its self-cleaning separator and robust construction. It performs reliably in extreme process conditions, ensuring stable long-term operation and improved process control.
