Fingertip pulse oximeter

Model Number: SE-PO-05 Key Specifications/Special Features: From professional pulse oximeter manufacturer/supplier/factoryFeatures:1. Color OLED display, simultaneous display for testing value and plethysmogram2. Manually adjust the direction of interface3. Visual alarm function. Real-time spot-checks4. Standard two AAA 1.5V Alkaline Battery is available for power supply5. Advanced DSP algorithm inside minish the influence of motion artifact and improve accuracy of low perfusion6. Accurately determine your SpO2 (blood oxygen saturation levels) and pulse rate within seconds;Specification:1. Install 2 AAA batteries;2. Place ring finger of non-dominant hand into opening with nail bed facing up3. Press button on the front panel4. Trembling fingers, nail polish and excess light can interfere with accuracy5. Read SpO2 and HR from display screen; make sure the pulse on the oximeter matches actual pulse, and that there is a strong, consistent wave graph or data may not be reliable
