H1 Pulse Oximeter

Specification:

Scope of application: ward monitoring, family health care, patient testing, outpatient medical care

Power requirements: 2 section 7th 1.5V alkaline battery (without battery)
Strong resistance to ambient light and weak perfusion
Display format: LCD display: blood oxygen saturation display: 70 - 100%, four orientations, 8 modes display; (respectively for the up, down, left and right fonts)
Pulse rate display: 30 - 240 BPM, 3-digit seven-segment digital display;
Pulse wave display: bargraph display;
Low battery voltage indication: LCD symbol.
Power requirements: 2 sections of the seventh 1.5V alkaline battery, voltage adaptation range: 2.6 - 3.6 volts.
Power consumption: less than 30 mA.
Resolution: Blood oxygen saturation is ±1% and pulse rate is ±1 BPM.
Measurement accuracy: Blood oxygen saturation is ±2% in the 70%-100% segment, less than 70% is undefined, and the pulse rate is ±2 BPM.
Measurement performance under weak perfusion: Blood oxygen and pulse rate values are correctly displayed at a pulse fill of 0.5%.
Resistance to ambient light interference: The measured value of blood oxygen in indoor natural light and existing illumination sources is less than ±1% compared to measurements in darkroom conditions.
