The Scope of Applications
The Fingertip Oximeter can monitor pulse oxygen saturation and pulse rate
through patient’s finger. This device is applicable to hospital, home, oxygen
bar, the community medical center, alpine area and it also can be used before
or after sports, and so on. This device is not appropriate to be used for
continuous monitoring.

1. Display mode: LCD display
Pulse wave’s intensity display: 16-segment digital display
Low battery voltage indication: Segment LCD signal

2. Measuring range:
Pulse: 30bpm-240bpm
SpO2: 50%-99%

3. Accuracy:
SpO2: ± 2% (during 80%-99%)
±3% (during 70%-79%)
