Display of the oxygen saturation : 70 ~ 100%,±2% *pulse power display: 25 – 250 bpm,±1% or ±1bpm,and Take the larger one
Power supply: 2 aaa 1.5v alkaline batteries; vol Age suitable range: 2.6 ~ 3.6v
Power consumption: less than 30ma
Measure precision: the oxygen saturation b Tween 70%-99%, the precision is ±2%; and less than
70% the precision has no definition; the pulse po Er is ±1% or ±1bpm,and take the larger one.
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%. *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%.
Have function switch, and it will stop automatically after 8 seconds without finger insert in.
