Principle of Operation:
Close-coupled extractive oxygen and combustibles
analyzer using zirconium oxide for oxygen measurement
and a catalytic detector for combustibles. Completely field serviceable.

Display Range:
Oxygen: 0.1-100%
Combustibles: 0-10,000 ppm or 0-5%
Output Range:
Oxygen: From 0-1% to 0-100%

Combustibles: From 0-2,000 ppm to 0-10,000 ppm
from 0-1% to 0-5%

Accuracy:
Oxygen: ±0.75% of measured value or ±0.05%
oxygen, whichever is greater
Combustibles: ±2% of full scale output range

Response:
Oxygen: 63% of a process step change <30 secs.
Combustibles: 63% of a process step change <30 secs.

Drift:
< 0.1% of cell output per month (< 0.005% O2 per month with 2% O2 applied)

Aspirator Air Requirements:
10 to 20 scfh (4.72 to 9.4 L/min.) at 15 to 100 psig

  • to 2600°F (1426°C) with mullite
  • to 3200°F (1760°C) with alumina

Probe Lengths:
36″ (91cm) to 108″ (274cm), 316SS or RA330
24″ (60cm) or 42″ (106cm), mullite or alumina

Max. Sample Dewpoint:
400°F (204°C)

Sample Pressure:
±2 psig: no adjustment required

Calibration Gas Requirements:
Use calibration gases @ 10 psig, 250 cc/min. (0.53 scfh)
O2 Span Gas:
Air or from 1.0% to 100% O2, balance N2
Zero and Comb. Zero Gas:
2% or from 0.1 to 10% O2, balance N2
Comb. Span Gas:
60 to 80% (ppm ranges) or 40 to 60% (% ranges) of the selected comb. recorder output range in certified mixtures of CO or CO + H2, excess O2, balance N2
