Under the epidemic, the best gift for parents to let them know their health better every day.
Just need two AAA batteries and you're all set. The screen is clear and easy to read. Prefer to keep it in my First Aid kit box. It just a must-have thing to self check you health, especially this year! The best gift choice for parents and love.

• 10 SECOND PULSE & OXYGEN METER CHECK. Pulse Oximeter Fingertip is a compact heart rate monitor and oxygen monitor that checks pulse rate & blood oxygen saturation levels (SpO2) quickly & accurately
• Our simple & ergonomic blood oxygen monitor accommodates all finger sizes, so both kids and adults can use it. A perfect blood oxygen saturation monitor for ages 12 and above.
• EASY-TO-READ DISPLAY. The Pulse Oximeter comes with a big digital LED display which shows your o2 saturation monitor readings in large, easy-to-read digits. There’s also a battery life indicator.
• Principal: Oxygenated blood absorbs light preferentially at 940nm (near infrared light), whereas deoxygenated blood absorbs light preferentially at 660nm(red light). A pulse oximeter works by passing a beam of red and infra-red light through a pulsating capillary bed and then measures the amount of red and Infra-red light emerging from the tissues via a sensor.

Features:

• OLED high-definition display screen. The high-definition display screen made of OLED organic light-emitting diodes can clearly graph the blood oxygen value, six display directions, and can display the high-definition pulse waveform diagram.
• Infrared detection, fast measurement in 8 seconds.
• Auto power off after no operation in 5 seconds.
