YX300 Fingertip Pulse Oximeter

1、Display mode: OLED
Display of the oxygen saturation : 70 ~ 100%，±2%
Pulse power display: 25 – 250 BPM，±1% or ±1BPM，and take the larger one
2、Power supply: 2 AAA 1.5V alkaline batteries; Voltage suitable range: 2.6 ~ 3.6V
3、Power consumption: less than 30mA
4、Measure precision: the oxygen saturation between 70%-99%, the precision is ±2%; and less than 70% the precision has no definition; the pulse power is ±1% or ±1BPM,and take the larger one.
5、Measure capability under the situation of weak perfusion: it 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 warp is less than ±1%.
7、Have function switch, and it will stop automatically after 8 seconds without finger insert in.
