CO/O2 GAS ANALYZER FOR STACK GAS
DATA SHEET
ZSQ
This instrument is equipped with a non-dispersive infrared
CO sensor and a zirconia O2 sensor. It is used for measuring CO and O2 in the gas emitted from a garbage incinerator to meet Japanese regulation on emission control of
dioxins (tetrachlorodibenzoparadioxins).
CO instantaneous value, O2 instantaneous value, CO instantaneous value after O2 correction and CO average values
after O2 correction (1-hour and time-variable averagings) can
be output, and a peak count/alarm function is incorporated.
FEATURES
1. Suitable functions for emission control of dioxins.
• Output includes CO instantaneous value, O2 instantaneous
value, CO instantaneous value after O2 correction and
CO average values after O2 correction (1-hour and timevariable averagings).
• Count/alarm function against excess over specified value
2. Space-saving configuration by unitizing the analyzer and
sampling device into 19-inch types.
3. Easy to maintain with auto calibration and with “From
the front maintenance construction”.
4. A microjet recorder (Fuji Electric’s type PHC or PHE) can
be built in for recording measured gas concentration and
temperature values.

Functions of Individual Components
• Gas extractor: Gas extraction, with heating type stainless steel filter having a standard diameter of 40µm
• Gas conditioner:
For separation of drain, prevention of
drain from being sucked through secondary filter and composite operation of constant-pressure bubbler.
• Gas aspirator: For aspiration of sample gas (sample gas
flow rate approx. 2R/min).
• Sampling module:
Incorporates electronic gas cooler, solenoid valve, membrane filter and flowmeter.
• Electronic gas cooler;
Dries the moisture in sample gas to a
dew point of approx. 2˚C.
• Solenoid valve;
Used for introducing calibration gas.
• Membrane filter;
Glass fiber and PTFE filter used to eliminate fine dust particles and permit
monitoring of dust adhering condition
on the front panel of the gas analyzer.
• Flowmeter;
Adjusts and monitors the flow rate of
sample gas.
4
• Standard gas: Reference gas used for calibrating zero
and span of the analyzer; air and CO for
span, and O2 for zero.
• Zirconia O2 sensor:
Zirconia oxygen sensor used for measuring the oxygen concentration (0 to 25%)
in sample gas.
• Solenoid valve for atmospheric air:
Can be built in for using the atmospheric
air instead of standard air.
