Finger Fingertip Pulse Oximeter Oxymètre Color OLED Display-50D
Finger Fingertip Pulse Oximeter Oxymètre Color OLED Display-50D 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, hrough which the Oximeter can be automatically powered off when no finger is in the Oximeter more than 8 seconds.
