INFRARED GAS ANALYZER
(LOW-CONCENTRATION MEASUREMENT TYPE)
DATA SHEET
ZPG
This gas analyzer (ZPG) is capable of measuring the
concentration of NO, SO2, CO2, CO and O2 components
in sample gas. NO, SO2, CO2, CO are measured by non-
dispersion infrared method (NDIR), While O2 is measured
by fuel cell or paramagnetic and zirconia method.
Through use of the sample switching system, ZPG is
capable of canceling drift in zero point of the measurable
component by NDIR.
Optimum use as an analyzer unit of measurement system
for gas separation process and atmospheric environment
measurement and combustion exhaust gas from refuse
incinerator and boiler, or gas from various industrial
furnaces.
FEATURES
1. High sensitivity
Equipped with the newest upgraded mass flow sensor.
It is measurable of 0-5ppm range by newly-designed
measurement unit.
2. Excellent stability
Due to adoption of sample switching method (note1).
It is capable of canceling drift in zero point of measur-
able component.
3. Easy maintenance
Single beam design simplifies maintenance and mini-
mizes maintenance costs compared with double beam
or similarly equipper GFC based system.
4. Small and light
The size is small 133x483x382mm (HxWxD) and light
(7kg). It is capable to measure one of NO,SO2,CO2,CO
components by NDIR and measure one of O2 compo-
nents by O2 sensor at once.
5. Extensive functions
Various optional functions are available such as auto
calibration control, atmospheric pressure correc-
tion, high and low concentration alarm, remote range
switch, and range identification signal,etc.
note1) Excellent long term stability due to sample gas
and relative gas introduced alternately to the
measurement unit.
