FLOW CURVE2
Notes:
1
sccm denotes Standard Cubic Centimeters per Minute. It is a unit for the flow rate at standard conditions of temperature and
pressure. 1000 sccm = 1 slpm.
2
slpm denotes Standard Liters per Minute. It is a unit for the flow rate at standard conditions of temperature and pressure.
1 slpm = 1000 sccm.
