Flowmeter O₂ N₂O AIR Four Tube

Notes:

▪ Flowmeter O₂ N₂O AIR Four Tube

▪ Flow range: O₂:(0.1-10)L/min; N₂O:(0.1-10)L/min; AIR:(0.1-12)L/min

▪ Rotating float

▪ Accuracy: ±10%FSL(p=1013hPa,T=20±3°C)(Each flow tube shall be calibated to ±10% of the indicated value for flow rates between 10% and 100% of full scale)

▪ Alarm function

▪ Oxygen Concentr-ation：21%-29%

▪ Leakage test: ≤5ml/min@200kPa

▪ Oxygen filling fast

▪ N₂O AIR switching function

▪ When oxygen is below a certain value, there is a cut-off function
