The device can accurately measure SpO2 and pulse rate in a +-2% tolerance

Technical-Specification:                                                                                               

Display format: LED

. SPO2: 35%-99% in 2-digital, 7-segment digital

. Pulse rate: 30BPM--240 BPM in 3-digital, 7-digital

. Pulse Wave: 6-segment bargraph

. Battery Voltage Low Indication: LED signals

. Power Requirements: 2AAA size 1.5V Alkine 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

Funtion:

.Operation is simple and convenient

. Small in volume, light in weight (total weight is about 50g including batteries) and convenient in carrying

. Power consumption is low and the two originally-equipped 2 AAA bateries can bde operated continuously for 30 hours

. Low voltage warning will be indicated in visual window when battery voltage is so low that normal operation of the Oximeter might be influenced
