INFRARED GAS ANALYZER
DATAꢀSHEET
ZFG
OVERVIEW
This gas analyzer (ZFG) is capable of measuring the concen-
trations of CO2, CO and CH4 components in sample gas.
Compact and lightweight design is intended, and a maximum
of 2 components are simultaneously measurable.
A high-sensitivity mass flow sensor is used in the detector
unit of infrared method. Due to use of single beam system
for measurement, maintenance is easy and an excellent
stability is ensured for a long period of time.
In addition, a microprocessor is built in and a large sized
liquid crystal display is provided for easier operation, higher
accuracy and more functions.
This analyzer is thus optimum for combustion control of
various heat treatment furnaces.

By setting an output hold to ON, analog
output signal is held in the value just
before the manual calibration.

is selected, and it is changed over to
the second range when the terminals
are open.
