EDS3-116E Datasheet, PDF (1/8 Pages) Fuji Electric – CO/O2 GAS ANALYZER FOR STACK GAS

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 measur-
ing CO and O2 in the gas emitted from a garbage incinera-
tor to meet Japanese regulation on emission control of
dioxins (tetrachlorodibenzoparadioxins).
CO instantaneous value, O2 instantaneous value, CO instan-
taneous 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 time-
variable 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.
