The is a highly specialized accessory designed for use with Ametek’s line of helium mass spectrometer leak detectors. Known as a "sniffer" probe, this device allows operators to perform qualitative leak detection on systems that cannot be placed under a vacuum (the "inside-out" method).

The 880-NSL simplifies calibration. An internal calibration filter allows for automatic electronic span checks without the need for bottled span gases. For a complete calibration, you can also introduce external zero and span gases through a dedicated port.
Usually indicates a plugged probe or a failure in the air aspirator. The is a highly specialized accessory designed for
is the current successor to the 880-NSL. Its manual and safety information can be found at the AMETEK 888 Resource Page General Support : For specific firmware or archived manuals, visit the AMETEK Service and Support calibration procedures Model 880-NSL Tail Gas Analyzer
Before diving into the manual itself, it is worth understanding why this analyzer commands such detailed documentation. The AMETEK Western Research Model 880-NSL (meaning “No Sample Line”) is a compact, rugged, transmitter-style analyzer that mounts directly on the process pipe. This innovative design eliminates the sample line, which has historically been one of the most problematic components in tail gas analysis due to sulfur vapor crystallization causing frequent plugging issues. The 880-NSL simplifies calibration
The system maintains accuracy with periodic automatic zero standardization using instrument air, keeping drift to less than of full scale over 24 hours. Operational Safety and Installation
The sample probe must be heated continuously using low-pressure steam (typically 35-50 psig) to keep the sample matrix above the sulfur solidification point (approx. 115°C / 240°F). Utility Connections:
If you’re searching for the , you’re likely working with one of the most reliable (yet complex) electrochemical instruments on the market. The 880-NSL is a potentiostat/galvanostat typically used in corrosion testing, battery research, and fuel cell development.
While you should always locate the exact revision for your specific unit, the 880-NSL user manual generally covers the following essential areas: A. Installation and Setup
