Overview
Introduction Combustion Experience ZP Oxygen Analyzer PCC-III Multiple Loop Controller Pricing Summary
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.
In-Situ Oxygen Probe
Thick cell Avoids premature cell failures
Ceramic heater provides reliable long life
Complete detailed diagnostics Automatic impedance checking
Alarms when time to recalibrate Alarms when reaching end of cell life
Optional fuel gas temperature element / T/C input
