How It Works
Clip it on your index finger, press the button, and you'll have a reading in under 10 seconds. The display shows your SpO2 (blood oxygen saturation) and pulse rate simultaneously. Normal SpO2 is 95–100% — anything below 90% warrants a call to your doctor.
Accuracy
FDA cleared means it's been tested against hospital-grade equipment. In independent tests, the Zacurate Pro consistently reads within ±2% of clinical devices, which is the accepted standard. Dark nail polish or acrylic nails can interfere — use a bare finger for best results.
Battery Life
Runs on two standard AAA batteries. Zacurate claims 30+ hours of continuous use, which in practice means the batteries last months with normal use. The unit auto-shuts off after 8 seconds of no movement to preserve battery.
