CHAPTER 1
Principles of Operation
1.1 General
The Model 7100P Portable analyzer by
Neutronics Inc. offers a cost effective
solution in a small package for oxygen
measurement and control applications.
The Model 7100P Portable analyzer is a
microprocessor based instrument
designed to accurately measure PPM
range oxygen. It is ideally suited for
measuring trace levels of oxygen in
applications including High Purity
Welding, Solder Reflow, Metal
Annealing, semiconductor furnaces,
glass manufacture, and inert atmosphere
chambers.
At the heart of the analyzer is a Neutronics Inc. micro-Zirconia ceramic oxygen sensor. The Zirconia
sensor is a solid state device which assures reliability and fast response for critical measurements.
Another advantage is since the sensor is a solid state device, it is unaffected by dry atmospheres, is
undamaged by extremely cold storage temperatures (or power down situations in cold environments),
and has indefinite storage life.
