EDS3-126A Datasheet, PDF (1/4 Pages) Fuji Electric – NDIR TYPE INFRARED GAS ANALYZER

NDIR TYPE INFRARED GAS ANALYZER
DATA SHEET
This infrared gas analyzer measures the concentration of
gas by utilizing the characteristic of gas (molecule consist-
ing of different-kind atoms) that it absorbs the infrared ray
of a specific wavelength.
Stable and accurate measurement is ensured due to use
of a mass flow sensor with a high sensitivity, interference-
compensating detector, etc. This analyzer is to be built in
sampling equipment and optimally usable for measuring
the concentrations of various gases.

FEATURES
1. Most suited for incorporation in equipment
This analyzer can be readily built in customer’s sampling
equipment, because its analyzing block, signal process-
ing circuit and power unit are all accommodated in a
compact case.
2. High measurement accuracy and stability
A single light source/double beam system, and a high-
sensitivity mass flow sensor ensure accurate and stable
measurement.
3. Minimum influence by other gases
An interference-compensating detector substantially
suppresses interference by the disturbing gases coex-
isting in sample gas.
4. Wide dynamic range
A range ratio of max. 1:20 can be secured in standard 2
ranges. Range selection follows the external selection
input signal.

Purging is required when combustible
and corrosive gases are contained in the
atmosphere or the range of CO2 is less
than 100ppm. In other cases, purging
should be made as necessary.

Mounting method: On table-top
Installation condition:
Install the analyzer at a place not ex-
posed to direct sunlight or the radiation
from a high temperature object. Avoid vi-
bration, and select a clean place free
from corrosive and/or combustible gas-
ses. If installing outdoors, provide a suit-
able casing or cover to protect the ana-
lyzer from wind, rain, etc.

ration occurs at 2°C (con-
densation unallowable).
Dust:
0.3µm or less (Recom-
mended membrane filter;
ZBBM6)
Pressure: 10kPa or less (Flow rate:
0.5L/min)(Gas outlet side
should be open to the at-
mospheric air)
Standard control for sample gas:
Calibration gas:
Dry gas
Interfere control gas: 2°C saturation
Measuring system:
Infrared-ray absorption method, non-dis-
persion, differential flow system, single
light source, double-beam system.
