EDS3-109E Datasheet, PDF (1/8 Pages) Fuji Electric – INFRARED GAS ANALYZER FOR STACK GAS

INFRARED GAS ANALYZER FOR STACK GAS
DATA SHEET
ZSP
This instrument consists of an (or two) infrared gas analyzer(s),
a zirconia O₂ sensor and a sampling device. It is used for
measuring the NOx, SO , CO and O components in the flue

gas of various boilers, garbage incinerators, furnaces, etc.
through a selective combination of the components.
The instrument has passed a type approval test in compliance
with regulations on measurement and weighing (specified in
Japan) of each component. It is extensively applicable as a
gas analyzer for environmental pollution control and com-
bustion control.
FEATURES
1. Simultaneous measurement of five components
A combination of two infrared gas analyzers plus a zirconia
0₂ sensor allows simultaneous measurement of four
components, NOx, SO₂, CO, CO₂ and O₂.
2. Easy operation with multiple functions
This analyzer can be equipped with a number of functions
such as auto calibration, O₂ correction and self-diagnosis.
It is easier to operate and maintain than a separate type
calculator system.
3. Little interference from other gases
Measuring error due to interfering gases contained in
sample is nearly zeroed by the Permapure dryer and
interference compensating detector adopted in the ana-
lyzer section respectively.
4. Excellent measuring accuracy and stability
The optical system is so constructed as to be free from
external stress by using a single light source and double
beam paths, and therefore assures improved measuring
accuracy plus excellent stability.
5. High sensitivity and wide dynamic range
The infrared gas analyzer, which mounts a mass flow
sensor, has a high sensitivity and a broad dynamic range,
and is capable of switching the measuring range to obtain
1:20 at maximum.
6. Reliable sampling system
Simple but reliable sampling system based on Fuji's rich
experience in the field enables easy maintenance and
reduces frequency of maintenance.
