7.5 4210D analyser performance
Sample requirements
For best performance the flow supplied to the analyser should be kept at a constant value for
both normal sampling and for calibration gas input.
Temperature: 5 to 40
°C / 41 to 104°F
Dew point 5
°C / 9°F below minimum ambient
Condition: Oil free, non - condensing, filtered to 2
m
Vent: Each sensor outlet should be connected to a separate
atmospheric vent, free from any back-pressure.
(Consideration should be given to the toxicity,
flammability and asphyxiant nature of the sample gas
when selecting a vent location).
Flow driven options:
IR : 100 (min) - 250 (max) ml/min
Pm Control: 100 (min) - 250 (max) ml/min
Gfx: 500 (min) - 2.500 (max) ml/min
Pressure driven options are not available.
WARNING
This analyser (4212D and 4214D) is not suitable for use with corrosive samples.
The auto-ignition temperature of each flammable gas in the sample must be greater
than 135
°C.
The maximum pressure to the analyser must be limited to 8psig by means of a
suitable release system.
CAUTION
Do not exceed the rated flow as sensor damage may result.
