1-5 Installation environment
(1) Ambient temperature : –20 to 55°C (Receiver unit/Transmitter unit), –5 to 45°C (control
unit)
(2) Ambient humidity : 90% R.H. or less
(3) Measurable optical path
length (stack diameter) : 0.5 to 10m (CO+O
2
: 0.5 to 5 m)
(4) Standard flange : JIS10K 50A flange (JIS B 2212)
(5) Air purge : Instrument air (compressor must be installed when power supply
cannot be provided.) (Oil or mist should not be contained), N

analyzer excluding air purge version
Pressure 0.5 to 0.7MPa or more 1.0 MPa or less
(6) Air purge flow rate : 20L/min or more (depending on the measured gas and velocity)
(7) Measured gas condition : Temperature: as specified in “1-1 (4) Measurable component and
range” of APPENDIX 1.
Pressure: ±10kPa
Moisture: 50vol% or less (or should not be saturated water vapor)
Velocity: 25m/s or less (However, consultation is necessary for the
environment where dust (1g/Nm
3
or more) or water (25vol% or
more) exists.) (Prevention of dust deposition or dew condensation
due to increase in air purge flow rate is required)

(9) Vibration : 0.5G or less (0.2G or less when the frequency range is 20 to 40Hz)
(When the optical path length is 1m.)
(10) Mounting angle : Horizontally ±5 degree or less (No dew condensation should accu-
mulate on the window.)
