Display Format: Colour LCD
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: +-% for SPO2 and +- 1BPM 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.
