In-Situ Oxygen Probe
No separate analyzer, one less item to mount
Field replaceable probeOnly one conduit to stack.

Proven Reliable Sensing element has been proven reliable in 100s
of 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 of
element cracking due to water Automated, menu driven pushbutton
calibration. Fully automatic calibration package available.
