Portable Finger Oximeter with One-Button Operation
The Portable Finger Oximeter is an economical and accurate device for measuring pulse rate and blood oxygen saturation (SpO₂) non-invasively through the finger. It features a clear display of the plethysmogram (pulse waveform) to ensure reliability, and a unique Perfusion Index (PI) that effectively reflects the pulsatile blood flow in the body. With simple one-button operation and a compact, portable design featuring an OLED screen, this oximeter is ideal for daily health monitoring at home or on the go.
Key Features
- Multi-Parameter Monitoring: Simultaneously displays four key parameters: SpO₂ (Blood Oxygen Saturation), PR (Pulse Rate), Pulse Waveform, and PI (Perfusion Index)
- Intelligent Display: Screen automatically rotates in 4 directions and supports 4 different display modes for optimal viewing from any angle
- User-Friendly Design: Lightweight, compact, and extremely easy to operate with a single button
- Clear Visualization: OLED screen clearly shows numerical values and SpO₂ waveform
- High Accuracy: Delivers precise readings with high sensitivity, even under low perfusion conditions (as low as 0.1%)
- Power Efficient: Powered by 2 AAA alkaline batteries, offering up to 20 hours of continuous use with automatic shut-off after 8 seconds of inactivity
