EDS3-108E Datasheet, PDF (1/16 Pages) Fuji Electric – MICROPROCESSOR BASED NDIR GAS ANALYZER

MICROPROCESSOR BASED
NDIR GAS ANALYZER
DATA SHEET
ZRF
This NDIR gas analyzer features a high accuracy, multiple
functions and easy operation through use of a microprocessor.
It also utilizes a mass flow detector noted for its high sensitivity
and reliability. Being housed in a 19 inch rack case suitable
for mounting on a panel or a table top, this analyzer is applicable
not only for measurement of environmental pollution but for
use in various processes and/or experimental laboratories.
FEATURES
(1) Use of a microprocessor provides high accuracy,
multiple functions and easy operation.
• The built-in automatic calibrating function allows
calibration of up to three components (option).
• The signal from a zirconia O₂ sensor (ZFK3) or
other O₂ meter enables output of an O₂ correction
value (option).
• Includes an alarm function providing an upper/
lower limit contact output (option).
• Range can be changed over by external signal
(option).
• Zero and span calibration is accurate and easy by
means of operating keys.
• A self-diagnosis function is included.
RS232C port available (option).
(2) This analyzer utilizes a mass flow detector featuring
high sensitivity and reliability. It is equipped with
two standard ranges for a range ratio of up to 1:20.
(3) Addition of a zirconia O₂ sensor (ZFK3) to the one/
two-component analyzer allows measurement of up
to three components simultaneously.
(4) Besides the standard method of measurement, a
sample switching system and differential flow
system are also available.
