Model 880-NSL Tail Gas Analyzer

Model 880-NSL Tail Gas Analyzer

Overview
AMETEK Process Instruments Model 880-NSL (No Sample Line) tail gas analyzer is a  compact, rugged, transmitter-style analyzer that mounts directly on your process pipe. The Model 880-NSL was designed using new technological advancements developed to meet your operational demands.  The 880-NSL photometer combines an extraordinary long lamp life (estimated 5 years!) with many innovative features designed to minimize maintenance and increase reliability. The 880-NSL is equipped with anti-clogging blowback features. The analyzer continuously monitors itself for proper operation and has built-in alarm features.


SAMPLE HANDLING AND ANALYSIS
The Model 880-NSL does not have an external sample line. The AMETEK Western Research Model 880-NSL mounts directly on the process pipe.

Designed for low maintenance sample and analysis, the 880-NSL photometer combines an extraordinary long lamp life (estimated 5 years) with many innovative features designed to minimize maintenance and increase reliability. Any analyzer fault conditions automatically initiates air blowback to clear the sample system. This feature minimizes the chance of costly downtime by reducing sample line plugging.

Ready to install worldwide with very modest utility requirements.
