INFRARED CO2 CONTROLLER
DATA SHEET
ZFP9
This is a non-dispersion type infrared CO2 gas analyzer. It
accurately measures the concentration of CO2 gas in the air,
indicates the result and simultaneously outputs an analog
signal. Since upper and lower limit alarm functions are standard it can also be used as a controller.
This instrument is suitable for use as a CO2 meter in green
houses, building ventilation systems, CA (Controlled Atmosphere) storage facilities, and so on.

CAUTIONS ON WIRING
Use vinyl insulated cable with a cross-sectional area of
1.25mm2 or more for the power supply and alarm contact
output.
Use two-core shielded cable for the output signal cable in
order to avoid the influence of inductive noise.
Be sure to connect shielded wires to the ground terminal.
Keep the output signal cable away from the power line and
alarm contact output line.
The product conforms to the requirements of the
Electromagnetic compatibility Directive 89/336/EEC as
detailed within the technical construction file number
TZ734574. The applicable standards used to demonstrate
compliance are :
EN 50081-1 : 1991 CLASS A Conducted and Radiated emissions
EN 50082-1 : 1992
