Pulse oximeter TEESA PX50 with OLED display — finger oxygen saturation and pulse measurement

TEESA PX50 pulse oximeter is a compact fingertip device with an OLED display that measures blood oxygen saturation (SpO2) and pulse rate non-invasively. Designed for spot checks at home, during travel or in light clinical screening, the oximeter provides real-time numeric readouts of SpO2, pulse and perfusion index on a bright OLED screen. Portable and battery-powered, the unit is suitable for adults and older children for monitoring respiratory status, recovery after exercise or basic wellness checks.

Advantages

The TEESA PX50 features a high-contrast OLED display for clear numerical results and an integrated red light sensor for accurate detection. It delivers a wide oxygenation measurement range with specified accuracy in common clinical intervals and provides pulse rate and perfusion index readings to help assess circulation. Lightweight and battery powered with low power consumption, the fingertip design enables quick, non-invasive spot measurements without additional setup.

Suitable for

• Home monitoring of blood oxygen saturation and pulse rate
• Spot checks during travel or outdoor activity
• Fitness recovery monitoring after exercise
• Basic respiratory screening in non-critical settings

How to use

Insert two AAA batteries into the compartment, ensure the device is switched off before inserting the finger, then place a clean finger fully into the oximeter clip so the sensor aligns with the fingernail. Press the power button to start measurement; numerical SpO2, pulse and perfusion index values will appear on the OLED display within seconds. Remain still during measurement and avoid excessive movement or ambient light directly over the sensor for more stable readings. After the reading, remove the finger and switch off the device to conserve battery.

Usage recommendations

Use the TEESA PX50 for occasional spot checks and trend observation rather than continuous clinical monitoring. For best results, use on a warm, rested finger with minimal nail polish or artificial nails. If readings are consistently outside expected ranges or symptoms are present, seek professional medical advice.
