 Technical Parameters 

■ Display Format: LCD                           ■  Back light: LED 

■  SPO2:35-99%                                       ■  Pulse Ratio:30-250 BPM 

■  Pulse Wave: LCD Graphic Display 

■  Battery Voltage Low Indication: LCD signals. 

■ Power Requirements: Two AA size 1.5V Alkali Battery; 

■ Power Consumption: less than 20 mA. 

■ Resolution: ±1% for SPO2 and ±1 BPM for Pulse Ratio. 

■  Measurement Accuracy: ±2% in stage of 70%-99% SPO2 and meaningless   when stage being 

     smaller than 70%. ±2BPM for Pulse Ratio.

■ Measurement Performance in Weak Filling Condition : Oxyhemoglobin     
    
     and pulse ＆ #118alue can be shown correctly when pulse-filling  ratio is 0.4%. 

■ Interference  Resistance  Capacity  against  Ambient Light :         
    
     Deviation  is  smaller  than  ±1% between #118alue of Oxyhemoglobin    
    
     measured in natural lighting indoor condition and present lighting  
  
     sources and  that measured in dark room.

■ It is equipped with a function switch, Through which the Oximeter     
    
    can be automatically powered off when no finger is in the Oximeter  more than 8 seconds.
