IN-SITU _{ZIRCONIA OXYGEN ANALYZER}
DATA SHEET
ZFK8, ZKM, ZTA
This oxygen analyzer is used to continuously measure
oxygen concentration in combustion exhaust gas of industrial
boilers or furnaces, and is ideally suited for combustion man-
agement and control.
The analyzer system is comprised of the detector and con-
verter coupled together as a complete system. Detector set-
ting configuration includes the detector flow guide tube and
detector sensor. The flow guide tube is inserted directly into
the gas and directs gas to the sensor for measurement. The
converter (ZKM) is comprised of the signal processor, input/
output and communications, display and system controls.
The converter is equipped with advanced functionality
such as performing the sensor diagnostics and sensor recov-
ery function, so the detector can be used within long term
stability.

FEATURES
1. Gas sampling device is unnecessary
For quick response, insert the detector directly into the
flue Gas sampling functions such as a gas aspirator and a
dehumidifier are not required.
2. Easy maintenance
The sensor equipped with the detector, has unit construc-
tion, it is easy to replace.
By separating the detector and the flow guide tube, filter
replacement is easy.
3. More reliable than sensor diagnosis, sensor recover-
able function
Depending on the concentration of the measurement gas,
the power of the sensor might deteriorate. The equipment
includes sensor recovery function electronically, checking
the deterioration status of the sensor depletion.
Therefore, it has high reliability and long-lasting stability.
4. Safe and secure
System detects thermocouple break for heater control on
the sensor side. Safety functions of isolating power supply
to the detector or isolating power via external contact input
are also.
5. Easy operation
The operation and setting for the converter can be per-
formed interactively, and available as English, Japanese or
Chinese for language display.
