EDS3-128 Datasheet, PDF (1/8 Pages) Fuji Electric – CO/O2 GAS ANALYZER FOR STACK GAS

CO/O2 GAS ANALYZER FOR STACK GAS
DATA SHEET
This instrument is equipped with a non-dispersive infrared
CO sensor and a galvanic oxygen sensor and used for
measuring CO and O2 in the gas emitted from garbage in-
cinerators.
CO instantaneous value, O2 instantaneous value and CO
average value after O2 correction (1-hour and time-variable
averaging) can be output.

FEATURES
1. The CO sensor adopts high-performance and long-life non-
dispersive infrared ray (NDIR) system. The CO sensor is
not consumable, and need not be replaced in 1 or 2 years.
2. Automatic calibration function by air equipped as stan-
dard allows stable measurement. No need to worry about
the consumption of standard gas.
3. Space-saving configuration unitized into 19-inch type al-
lows the maintenance from the front.
4. A microjet recorder (Fuji Electric’s type PHC or PHE) can
be built in for recording measured gas concentration and
temperature values.
