COMPACT TYPE GAS ANALYZER
DATA SHEET
ZSVF
OVERVIEW
The compact type gas analyzer (ZSVF) consists of an ana-
lyzing block (infrared sensor and oxygen sensor) and a sam-
pling block.
For gas extractor, either simplified measurement (non-fixed
type) or continuous measurement (fixed type) probe is se-
lectable at option.
Because a single beam type high-sensitivity mass flow sen-
sor is adopted for the infrared sensor, long-term stability
and maintainability are excellent.
This analyzer is capable of simultaneously measuring max.
5 components among NOx, SO2, CO2, CO, CH4 and O2 in
sample gas, and is used for flue gas from stationary emis-
sion sources such as various boilers, garbage incinerators
and heat treatment furnaces, and for plant cultivation and
research-purpose chemical analysis.
FEATURES
1. Gas concentrations of 5 components measurable simul-
taneously and continuously (Note).
SPECIFICATIONS
Standard Specifications
Concentrations of max. 4 gas components among NOx,
SO2, CO2, CO and CH4 are continuously measurable with
the infrared sensor, and that of O2 is continuously mea-
surable with a magnetic force or galvanic cell type oxy-
gen sensor in combination with a full-fledged sampling
block.
• Measuring system:
NOx, SO2, CO2, CO and CH4; Non-disper-
sive infrared absorption method with
single light source and single beam (single
beam method)
2. Standard with 3-range analyzer
Measurement can be performed over a broad range us-
ing the range selector key.
3. Compact type small and easy to use.
O2; Magnetic force or galvanic cell method
• Measurable component and min./max. measuring range:
NOx; 0 to 500 ppm / 0 to 5000 ppm
SO2; 0 to 500 ppm / 0 to 1 %
CO2; 0 to 200 ppm / 0 to 100 %
CO; 0 to 200 ppm / 0 to 100 %
CH4; 0 to 1000 ppm / 0 to 100 %
O2; 0 to 5 % / 0 to 25 %
Max. 5 components measurable includ-
ing O2
• Number of measuring ranges:
3 ranges
The analyzing block and sampling block are separated from
each other to facilitate transport and installation.
Operation is easier because operation keys and display
unit are all gathered in the analyzing block.
4. A rich variety of standard functions incorporated.
Auto zero calibration and auto drain discharge function
are incorporated for ensuring an excellent maintainabil-
ity.
Max. 8-channel outputs are allowed including instanta-
neous concentration value, O2-corrected value, O2-cor-
rected moving average value and CP calculation value
outputs.
• Max. range ratio 1:5
• Warm-up time: 30 min after power-on
Provided with count-down timer indicat-
ing function.
• Analog output: In up to 8 channels.
4 to 20 mA DC or 0 to 1 V DC (linear)
Non-isolated output
(Note) To perform measurement continuously, the standard
requirements for sample gas (shown on page 3) need
to be met, and periodic draining, zero/span calibra-
tions and membrane filter replacement are required.
Allowable load; 4 to 20 mA DC, 550Ω or
less
0 to 1 V DC, 100 kΩ or
more
This product is not explosion-proof. When handling dangerous gas, adequate attention shall be paid.
