â– Pulse Ratio:30-250 BPM
â– Pulse Wave: LCD Graphic Display
â– Battery Voltage Low Indication: LCD signals.
â– Power Requirements: Two AA size 1.5V Alkali Battery;
â– 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.
â– 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.
