finger oximeter

Pules O SPO2

MD-FO < for finger >


* Display Format: LED
　　　.SPO2:35-99% in two-digit 7-segment digital;
　　　.Pulse Ratio:30-240BPM in 3-digit 7-segment digital;
　　　.Pulse Wave: 6-segment barograph;
　　 .Battery Voltage Low Indication: LED signals.


* Power Requirements: Two AAA size 1.5V Alkali Battery;
　　
* Power Consumption: less than 40mA.
　　
* Resolution: ±1% for SPO2 and ±1 BPM for Pulse Ratio.
　　
* Measurement Accuracy: ±2% in stage of 70%-99% SPO2 and meaningless when
　　　stage being smaller than 70%. ±2 BPM for Pulse Ratio.
　　
* Measurement Performance in Weak Filling Condition: Oxy haemoglobin and pulse
　　　value 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 Oxy haemoglobin 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
