FUJI EDS3-126A

NDIR TYPE INFRARED GAS ANALYZER
DATA SHEET
ZRC6
This infrared gas analyzer measures the concentration of
gas by utilizing the characteristic of gas (molecule consisting 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, interferencecompensating 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 processing 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 highsensitivity 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 coexisting 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.

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 exposed to direct sunlight or the radiation
from a high temperature object. Avoid vibration, and select a clean place free
from corrosive and/or combustible gasses. If installing outdoors, provide a suitable casing or cover to protect the analyzer from wind, rain, etc.

should be open to the atmospheric air)
Standard control for sample gas:
Calibration gas:
Dry gas
Interfere control gas: 2°C saturation
Measuring system:
Infrared-ray absorption method, non-dispersion, differential flow system, single
light source, double-beam system.
