There are certain applications where an in situ oxygen probe is impractical. For those applications SSi recommends the HP2000 self-heated oxygen probe. This system supplies the temperature required to make an oxygen probe function. For some applications, such as a multi-tube generator or a rotary retort furnace, this probe will allow you to extract a continuous sample of the atmosphere stream and pass it by a standard oxygen probe. Applications:

• Rotary Furnaces Sample line extended into furnace beyond quench chute
• Opposite-end from atmosphere introduction
• Adequate filter system
• Conservative addition of enriching gas
• Manifold “sample” lines
• Allow for condensation drip
• Fixed sample lines
• Low temperature applications
• Nitrogen-based low temperature, miscellaneous protective atmospheres
• %Oxygen in residual combustion gases.
• Manual “shut-off” valves are suggested
