EDS3-136 Datasheet, PDF (1/16 Pages) Fuji Electric – INFRARED GAS ANALYZER FOR STIC GAS

INFRARED GAS ANALYZER ^{FOR STIC GAS}
DATA SHEET
ZSK
This infrared gas analyzer (ZSK) is composed of gas ana-
lyzer units, oxygen sensor and gas sampling equipment.
It is capable of continuous measuring concentration of
gases such as NOx, SO2, CO, CO2 and O2 contained in
the flue gas generated from various boilers or garbage
incinerators.
FEATURES
1. Gas concentrations of 5 components measurable
simultaneously and continuously
The infrared ray method has integrated the measurements
of NOx, SO2, CO and CO2 and the gas concentrations
of 5 components can be measured simultaneously and
continuously with the zirconia oxygen analyzer.
2. A high-sensitivity mass flow sensor is used in the
detector unit of infrared method.
Due to use of single beam system for measurement,
maintenance is easy and an excellent stability is ensured
for a long period of time.
3. Space-saving configuration is available with the
maintenance from the front structure
The main unit is downsized by half of that of the conven-
tional product. The complete maintenance from the front
makes it easy to use.
4. The analyzer has a host of capabilities
Provided with a variety of functions such as O2 correction
output, average value output, auto calibration, auto range
selection, alarm, etc.
