| （*1） The gases must be dry and clean, free of corrosive components and foreign matter such as dust and mist. | ||||
| （*2） The flow rate calibration units SCCM and SLM indicate a mass flow rate converted to a volume flow rate in cc/min and L/min at 0°C and 1 atm. | ||||
| （*3） The operating differential pressure may differ depending on specifications. | ||||
| （*4） Pressure condition would be needed when you order. | ||||
