1.3 Features

The Model 2120XL comes equipped with the following standard

features:

 A 2-line alphanumeric vacuum fluorescent display (VFD)

screen, driven by microprocessor electronics that
continuously prompts and informs the operator.

 High resolution, accurate readings of nitrogen content from

low ppm levels through 100 ppm in argon. Large, bright,
meter readout.

 Advanced high frequency plasma generator produces stable

electroluminescent discharge with minimal heating yielding a
spectral emission characteristic of the gas mixture.

 Custom low-noise optical filter for precise narrow band

selection and low optical interference.

 Amplified optics circuit for stable nitrogen detection at low

ppb level.

 Microprocessor based electronics: 8-bit CMOS

microprocessor with 32 kB RAM and 128 kB ROM.

 Three user definable output ranges (from 0-1 ppm through 0-

100 ppm) allow best match to users process and equipment.

 Auto Ranging allows analyzer to automatically select the

proper preset range for a given measurement. Manual
override allows the user to lock onto a specific range of
interest.

 Two adjustable concentration alarms and a system failure

alarm.
