Model Number

EX-933;

1.Anaesthesia system

Flow meter

Adjusting range
O2               0.1～1 L/min、1～10 L/min
N2O             0.1～1 L/min、1～10 L/min
Accuracy (20℃　101.3kPa)
Above 1L/min     ±10％ of indicated value
Below 1L/min         Class 4
Interlocked control of O2 and N2O  flows O2 and N2O flow meters interlocked for
          proportional adjustment. O2 concentration be ≥25 %.

Quick oxygen supply
Quick oxygen supply flow        35 L/min～ 75 L/min

Enflurane evaporator and isoflurane evaporator

Concentration adjusting range        0.5％～5％
With temperature and flow self compensation functions
Oxygen emergency alarm and laughing gas cut-off protection
When O2 pressure is lower than 0.2 MPa, an alarm will be given lasting at least for 7s and N2O supply will be cut off.
