Features
The LI-800 is an economical high performance, non-dispersive infrared gas analyzer designed
to be used for a wide variety of applications. Some of the LI-800's important features include:
●
Optional short (2") and standard long (5.5") interchangeable optical benches can be used
to obtain resolutions of 0-20000 ppm and 0-2000 ppm, respectively. No changes in
calibration polynomials or software need to be made when swapping optical benches.
●
Optical benches are fully serviceable by the user; cleaning the optical benches is a simple
process, and does not affect the instrument calibration.
●
Simple Windows
®
software provides for easy user calibration and data output.
Precautions
●
The optical bench is maintained at a constant 50 °C. Avoid direct exposure to sunlight or
extremely high temperatures that may elevate the temperature inside the LI-800 case.
●
The optical source is sensitive to vibration, and can be damaged by strong vibrations or
jarring. Do not drop the LI-800, or expose it to severe mechanical shock.
●
Do not use abrasive cleansers when cleaning the optical bench, as damage to the gold
plating may result. Instructions for cleaning the optical bench can be found in Section 5.
●
Always filter air entering the LI-800. A Gelman polypropylene filter is included in the
spares kit.
