Specification

Performance
Accuracy 0.2 ppm from 0 to 10 ppm or ±2% of reading
Repeatability ±1% of reading
Response time Less than 2 seconds for 90% step change
Stability Less than 3% of reading per year
Pressure effect Less than 0.2% of reading per mm Hg
Sample flow rate influence Per 40 cc/min flow change at 400 cc/min 0.2 ppm from 0 to 10 ppm or 2% of reading
Background gas variation effect Sample gas must be clean, dry and free of combustibles. For best results used same background gas for calibration. Standard factory calibration is 5 ppm O2 in N2.
