EDS3-117 Datasheet, PDF (1/2 Pages) Fuji Electric – PORTABLE GAS ANALYZER

PORTABLE GAS ANALYZER
DATA SHEET
This unit is a simple and stable analyzer using a single-beam
infrared-ray system. It is designed for measuring carbon
dioxide gas (CO2), carbon monoxide (CO) or methane (CH4),
and is used to measure atmospheric gases in agricultural
vinyl greenhouse, carbon dioxide gas in rooms or carbon
dioxide gas, carbon monoxide, ethane, etc., in thermal pro-
cessing furnaces.

FEATURES
1. Single-beam NDIR system is used for simple structure,
providing excellent stability without interference of other
gases.
2. The adoption of a unique mass-flow type sensor assures
high sensitivity and long service life.
3. One-touch zero/span calibration, self-diagnosis function
and 2-range select function assure easy operation and
maintenance.
4. Sampling devices such as pump, filter, flow checker, etc.,
are built-in to allow the user to make measurements sim-
ply by connecting a sampling tube.
5. Compact design offers easy carrying and handling.
