Maintain Rate
The chart below shows typical flow rate required to maintain the oxygen content at
different percentages of concentration in the RBC1-50 Burn-In oven with
nitrogen
atmosphere option installed. For example, it requires 36SCFH to keep the oxygen
concentration down to 6½ percent in the closed oven chamber. The preliminary
settings can be determined from this graph. If the oxygen concentration must be
determined more accurately, use an oxygen monitor.
