■  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, hrough which the Oximeter can be automatically powered

off when no finger is in the Oximeter more than 8 seconds.
