BULLETIN 880-NSL

Model 880-NSL Tail Gas AnalyzerTHE NEEDAMETEK Western Research®, the leader in tail gas analysisfor over 25 years, is proud to introduce Model 880-NSL(No Sample Line) tail gas analyzer. This compact, rugged,transmitter-style analyzer mounts directly on your processpipe. The Model 880-NSL was designed using newtechnological advancements developed to meet youroperational demands. The analyzer mounts directly onyour process pipe, eliminating sample line plugging. The880-NSL photometer combines an extraordinary long lamplife (estimated 5 years!) with many innovative featuresdesigned to minimize maintenance and increase reliability.The 880-NSL is equipped with anti-clogging blowbackfeatures. The analyzer continuously monitors itself forproper operation and has built-in alarm features.

APPLICATIONS• Sulfur recovery units

• Claus process

• Claus with tail gas cleanup

• Claus with oxygen enrichment

SAMPLE HANDLINGAND ANALYSISThe Model 880-NSL does not have an external sample line.The AMETEK Western Research Model 880-NSL mountsdirectly on the process pipe.

Designed for low maintenance sampling and analysis,the 880-NSL photometer combines an extraordinary longlamp life with many innovative features designed to minimizemaintenance and increase reliability.

Anti-Clogging and Blowback Features

Any analyzer fault conditions automatically initiates airblowback to clear the sample system. This feature minimizesthe chance of costly downtime by reducing sample lineplugging.

Integrated Worldwide Design

Ready to install worldwide with very modest utilityrequirements.

Self Diagnostics

Continuously monitors itself for proper operation and hasbuilt-in alarm features.

SUPERIOR BENEFITS• No sample line
