COMPACT TYPE GAS ANALYZER
DATA SHEET
ZSVS
OVERVIEW
The compact type gas analyzer with built-in pump and filter
is intended for heat treat furnace, plant cultivation, and re-
search-purpose chemical analysis. With the gas extractor,
either simplified measurement probe (non-fixed type) or con-
tinuous measurement probe (fixed type) is selectable at
option. Since a high-sensitivity single-beam mass flow con-
troller is adopted for the infrared sensor, long-term stability
and maintainability are excellent.
FEATURES
1. Gas concentrations of 4 components measurable simul-
taneously and continuously (Note).Concentrations of max.
3 gas components among CO2, CO and CH4 are continu-
ously measurable with the infrared sensor, and that of
O2 is continuously measurable with galvanic cell type
oxygen sensor.
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.
The compact body with built-in pump and membrane filter
is easy to carry and install.
Operation is easier because operation keys and display
unit are all gathered in the analyzing block.
4. A rich variety of standard functions incorporated.
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.
(Note) For continuous measurement, the standard require-
ments for sample gas (shown on page 3) need to be
met, and zero/span calibrations and membrane filter
replacement are required periodically.
