Finger Pulse Oximeter SPO2 PR PI RR Monitoring Blood Oxygen Saturation Monitor Features:  The Fingertip Pulse Oximeter can be used to oxygen saturation, pulse monitoring, PI perfusion index, breathing frequency. One-click measurement, quick detection. OLED Energy Saving Display Screen - You can see it in the dark. Accurate infrared measurement, no blood collection, high safety. Abnormal data alarm - A warning is issued when the blood oxygen saturation exceeds 94-99% and the heart rate exceeds 60-130times/min. High speed computing chip, make sure the results are fast and accurate. PI Perfusion Index Measurements Function - The larger the pulsating blood flow is, the more pulsating component is, and the larger the PI value is. Lightweight and compact, easy to carry. Widely used in hospital, home healthcare, oxygen bar, community medical centre,  sports healthcare, etc. Specification: Item Type: Fingertip Pulse Oximeter Material: ABS+PC Color: Silver+Black SPO2: Measuring Range: 70%-99% Accuracy: Within ±2% Unspecified: ≤70% Analysis Rate: ±1% Pulse repetition frequency:  Measuring Range: 30 - 240bpm Accuracy: ±1bpm Perfusion Index: ≥0.2%,±0.1% Power consumption: <30mA Operating Temperature: 5℃-40℃ Relative Humidity: 15%-80% on operation, 10%-80% in storage Atmospheric pressure: 70Kpa~106Kpa Battery Type: 2 * AAA Battery(Not Included) Package List: 1 * Main Machine 1 * Hang Strap 1 * Manual
