LED can be used to measure human Hemoglobin Saturation and heart rate through finger in rotary directions, and the Hemoglobin Saturation Volume wave can be displayed when the Hemoglobin Saturation and heart rate are displayed in horizontal direction. The product is suitable for use in family, hospital, Oxygen bar, social medical organizations and physical care in sport and etc.

System Characteristics:
◆      Simple and convenient operation;
◆      Low voltage warning will be 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 when no signal is in the product for longer than 8 seconds;
◆      Super low power consumption;
◆      Portable.

Technical Specification:
 ◆ Display format: LED

 ◆ 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
