INFRARED CO2 CONTROLLER
DATA SHEET
ZFP9
This is a non-dispersion type infrared CO₂ gas analyzer. It
accurately measures the concentration of CO gas in the air,
2
indicates the result and simultaneously outputs an analog
signal. Since upper and lower limit alarm functions are stand-
ard it can also be used as a controller.
This instrument is suitable for use as a CO meter in green
2
houses, building ventilation systems, CA (Controlled Atmos-
phere) storage facilities, and so on.
FEATURES
1. Use of high-performance infrared-ray system
2. Excellent stability and easy maintenance
3. Control with upper/lower limit alarm functions possible
4. Compact and lightweight (Approx. 3kg)

Alarm hysteresis width; ± 4% of scale
length (at 50% FS)
Indication; upper limit indicator lamp (red)
— lights up when CO₂ concentration
exceeds upper limit.
lower limit indicator lamp (red)
— lights up when CO₂ concentration
is below the lower limit.
