Pulse Oximeter

1-Display mode: OL
Display of oxygen saturation: 70~100%,±2%Pulse power display: 25~250BPM,±l%or±lBPM,and take the large one
2-Power supply: 2 AAA 1.5V alkaline batteries,
Voltage suitable range: 2.6~3.6V
3.Power consumption: Less than 30ma
4.Measureprecision: The oxygen saturation between 70%-99%,the precision is ±2%;and less than 70% theprecision has no definitioathe pulse power is ±1% or ±lBMP,and take the lager one.
5.Measure capability under the situation of weak perfusion: Tt can rightly display the oxygen saturation and the pulse power when the pulse fullness degree is 0.6%.
6.Compared to the measure value in the darkroom,the oxygen saturation in the natural light and the illuminate light-house,the wap is less than ±l%.
7.Have function switch, and it will stop automatically after.
8.seconds without finger insert in.
