1.3 Typical Applications
The Model 300P Percent Oxygen Transmitter is capable of monitor-
ing oxygen at the % level in a variety of gases. It is widely used in indus-
try. A few typical applications are:
• Monitoring inert gas blanketing
• Air separation and liquefaction
• Chemical feedstock analysis
• Semiconductor manufacturing
• Petrochemical process control
• Heat treating and bright annealing processes
• Quality assurance
• Gas certification
• Welding applications
• Flue gas analysis.
