. 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 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

. 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 bde indicated in visual window when battery voltage is so low that normal operation of the Oximeter might be influenced
. The product will automatically be powered off
