EDS3-110D Datasheet, PDF (1/16 Pages) Fuji Electric – NDIR TYPE INFRARED GAS ANALYZER

NDIR TYPE INFRARED GAS ANALYZER
DATA SHEET
ZRG
This NDIR gas analyzer features high accuracy, multiple
functions and easy operation through use of a microproces-
sor. It also utilizes a mass flow detector noted for its high
sensitivity and reliability.
This analyzer is used not only for measuring environmen-
tal pollution but is also used for various processes and/or
experiments.
This product, combined with sampling system (ZSP), has
passed the type-approval test based on Weight and Mea-
sure Act.
FEATURES
(1) Use of a microprocessor provides high accuracy, mul-
tiple functions and easy operation.
• A maximum of 3 gas components can be calibrated
with the built-in automatic calibrator (option).
• Using a signal from a zirconiz O sensor (ZFK3) or from
2
any other O₂ sensor, the gas analyzer is able to out-
put a value converted into O₂ (option).
• Alarm function to emit high/low limit contact output
is also available (option).
• Measuring range can be selected by using external
single (option).
• Zero and span can be calibrated with high accuracy,
simply by pressing calibration keys.
• A self-diagnosis function is included.
(2) This analyzer utilizes mass flow detector featuring high
sensitivity and reliability. It has 2 standard measuring
ranges with a range ratio of up to 1:20.
(3) Three different gas components can be measured si-
multaneously by connecting a zirconia O₂ sensor (ZFK3),
in addition to one-and two-component type sensors.
(4) Besides the standard measurement type, a sample swi-
tching type and a differential flow type are also available.
