Portable Fingertip pulse oximeter (WLX503)
Features
1. Display parameters: blood oxygen SPO2 value, heart rate pulse PR value, histogram, blood perfusion index PI
2. Display screen: the product adopts TFT LCD screen display
3. Energy saving and environmental protection: The product has low power consumption, and the two AAA batteries
can be used continuously for more than 48 hours
4. Voltage warning: when the battery voltage is too low, it may affect normal use, there will be a low voltage warning
prompt
5. One-key boot: One-key boot function, simple operation
6. Automatic shutdown: When no signal is detected, the product will automatically shut down after 8 seconds into an
energy-saving state.
7. Advantages: Integrating blood oxygen probe and processing display module, the product is simple to use, low
power consumption, small in size, light in weight and easy to carry
8. Blood oxygen measurement range (SPO2): 0~100% (accuracy ±2%, less than 70% undefined) 100%> normal> 94%
≥ insufficient oxygen supply
9 Pulse measurement range (PR): 30~250bpm (accuracy ±2bpm or 2% whichever is greater) 60bpm≤normal≤
90bpm
10 Blood Perfusion Index (PI): The greater the pulsating blood flow, the greater the pulsating component, and the
greater the PI value (currently there is no uniform range)
