Gas measure : O2
Measuring principle : Paramagnetic (partial pressure measurement with rotatable glass dumbbell)
Standard gas Ranges :
-
0-1% / 0-5% / 0-25% / 0-100% vol O2 (SERVOMEX detector integrated in heated enclosure)
-
95-100% vol O2 for pressurized applications (heated MBE detector version)
Low detection level : 0.01% vol O2
Repeatability ≤ ± 0.5 % of full scale
Zero and Span Drift ≤ ± 1% of Full Scale/week
Auto-zeroing cycle : programmable by software (internal air pump)
Note : 4-20mA output is frozen during automatic zeroing cycle + 120 sec.
Response time (TD + T90) < 10 s (gas flow dependent)
Warm up time : 600 seconds
Calibration :
-
5 points factory calibration stored in the microprocessor of the gas analyzer
-
2 points (zero and span) user calibration
Sample Gas Conditions :
