A smart and tiny device that can prevent heart attacks and strokes! Introducing the 2 In 1 Flash-Check Finger Pulse Oximeter which is convenient to measure oxygen saturation (SO2) and pulse rate instantly with only a fingertip scan.

Without breaking into the skin, it is quick and safe to use. It is convenient for patients with asthma and heart diseases to have close monitoring of medical conditions. With the small and portable size, the device is also great for sports enthusiasts to have it around when doing extreme sports.  


  • Instantly Measure: With the quick and precise sensor, it can determine your blood oxygen saturation level and pulse rate instantly with clear reading.

  • Easy To Use: Only a simple setting is required - one button operation. Alarm notification will be effective when there is high / low measurement.

  • Readable LED Display:
    The measurements will be displayed on a large and clear LED digital screen for easy reading. It is great for the elderly or people with sight problems.

  • Great For Sports Enthusiasts: 
    It is suitable for sports enthusiasts when doing extreme sports like mountain climbers, skiers, bikers or anyone interested in measuring their SpO2 and pulse rate during exercises.

  • Easy To Carry:
    The device is small and lightweight to carry around. It is made of durable ABS with a neck strap
  • Suitable For All Ages:
    The device fits a wide range of finger sizes from infants, children to adults.


    How to measure:

    • Normal blood oxygen levels are considered 95-100 percent.
    • Between 90 and 95 percent, your blood oxygen level is considered low but it is not necessarily indicative of a health issue.
    • If the level is below 90 percent, it is considered low resulting in hypoxemia.
      The causes of hypoxemia can be sleep apnea, asthma crisis, pulmonary infection, etc.

      How does it work?

      Plethysmograph - The SpO2 Waveform

      Each wave corresponds to a heartbeat and the amplitude to the amount of blood detected in your blood vessels. When the wave amplitude is consistent (as shown in the figure), the pulse oximeter is optimized and readings can be taken.

      Perfusion Index

      The Perfusion Index (PI) informs you of the strength of your pulse. If the PI value is less than 0.2%, this means that your hands are either too cold or improperly positioned in the pulse oximeter. Simply warm your finger and reposition it so that it is right between the LED light and sensor. No more second guessing if the readings are reliable or why the pulse oximeter is not giving a reading.

      Frequently Asked Questions:

      • Q: Can the user set the parameters for the alarms? Can the alarms be set even if the 'beep' of each beat is turned off?
        A: Yes to both questions. Users are able to set parameters and/or change settings for the alarms and control the beeps of the alarm according to your preferences.
      • Q: Can I wear this device while I run?
        A: No. You should only use the pulse oximeter before or after your exercise routine. Also, you should remain stationary while the pulse oximeter measures your pulse and SpO2.
      • Q: Can this pulse oximeter be used on children?
        A: Yes, as long as the finger is big enough to fit into the pulse oximeter. Generally, it should fit children 12 and above.
