Detailed Product Description

Display format: LED
SPO2: 3599% in 2-digit 7-segment digital.
Pulse rate: 30240 BPM in 3-digit 7-digital.
Pulse Wave: 6-segment bargraph.
Bettery Voltage Low Indication: LED signals.
Power Requirements: 2AAA size 1.5V Alkline Battery.
Power Consumption: Less than 40mA.
Resolution: +-1% for SPO2 and +-1 BPM for Pulse rate.
Measurement Accuracy: +-2% in stage of 70%-99% SPO2 and meaningless when stage being smaller than 70%, +-2% BPM for Pulse rate.
Measurement Performance in Weak Filling Condition: Oxyhemoglobin and pulse rate can be shown correctly when pulse-filling ratio is 0.5%.
Interference Resistance Capacity against Ambient Light: Deviation is smaller than +-1% between value 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.
