Ametek WDGIVCM
Principle of Operation:
Close-coupled extractive oxygen, combustibles and methane analyzer using zirconium oxide for oxygen
measurement and catalytic detectors for both
combustibles and methane. Completely field serviceable.
Display Range:
Oxygen: 0.1-100%
Combustibles: 0-10,000 ppm
Methane: 0-5%
Output Range:
Oxygen: From 0-1 to 0-100%
Combustibles: From 0-2,000 ppm to 0-10,000 ppm
Methane: 0-5%
Accuracy:
Oxygen: ±0.75% of measured value or ±0.05% oxygen, whichever is greater
Combustibles: ±2% of full scale output range
Methane: ±5% of full scale output range
Response:
Oxygen: 63% of a process step change < 3 secs.
Combustibles: 63% of a process step change < 7 secs.
Methane: 63% of a process step change < 12 secs. without flame arresters, < 30 secs. with flame arresters
Drift:
< 0.1% of cell output per month (< 0.005% O2 per month with 2% O2 applied)
