Summary
In-Situ Oxygen Probe
No separate analyzer, one less item to mount
Field replaceable probe
Only one conduit to stack.
In-Situ Oxygen Probe
Proven Reliable
Sensing element has been proven reliable in 100sof installation over the last 10 years
No Reference Air
The probe uses ambient air as a reference.
Competitors use instrument air and run the risk ofelement cracking due to water
Automated, menu driven pushbuttoncalibration.
Fully automatic calibration package available.
