Fingertip Pulse Oximeter

This device offers quick, non-invasive spot-checks for blood oxygen saturation and pulse rate. It features an adjustable-brightness OLED display that clearly shows SpO2, pulse rate, a pulse bar, and a plethysmogram. With six display modes, you can easily switch views in any direction and choose between the plethysmogram or pulse bar. It measures SpO2 from 70% to 99% with ±3% accuracy and detects pulse rates from 30 to 235 BPM with ±2% accuracy. The OLED screen has 10 brightness levels for better visibility, and the low-power design includes automatic shut-off to save battery life. Powered by two included AAA batteries with a low-battery indicator, it requires no regular calibration or maintenance apart from battery changes. Lightweight at just 50 grams, it comes with a neck lanyard for convenience, has compact dimensions of 56 x 32 x 34 mm, and is suitable for both adults and children.
