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
