Keeping tabs on your blood oxygen and heart rate just got easier with this fingertip pulse oximeter.

It’s designed to be as accurate as the gear they use in hospitals, thanks to medical-grade sensors and smart chips.

You just slide your finger in, press the button, and within seconds you’ll see your SpO2 levels (0–100% with ±2% accuracy) and heart rate (30–250 bpm with ±2 bpm accuracy) on a bright 1.2-inch OLED screen.

It also shows perfusion index, which helps you know if you’re getting a good reading.

The spring-clip design keeps it snug on your finger, so you can even use it during light exercise or while sleeping—it’s got an alarm feature that can alert you if your levels go outside your set range.

It’s tough, too: waterproof, drop-resistant, and made with industrial-grade materials.

Comes with a case, lanyard, batteries, and manual.

Works for adults and kids over 1 (just use their thumb or big toe).

Whether you’re monitoring recovery, tracking fitness, or just want peace of mind, this little device is a reliable companion.
