COLMI RING 2 smart ring maat 9 zwart - 24/7 hartslag, SpO2, temperatuur, IP68, 7 dagen accu

The COLMI RING 2 redefines wearable health tracking by packing clinical-grade sensors into a sleek, durable ring that weighs less than a coin. Unlike bulky wristbands or smartwatches, this ring sits unobtrusively on your finger, capturing continuous heart rate, blood oxygen, body temperature, and sleep metrics without interrupting your daily routine. Its ceramic and stainless steel construction ensures comfort for all-day wear, while IP68 waterproofing means you never need to remove it—whether washing hands, showering, or swimming.

Highlights

• 24/7 heart rate monitoring with PPG sensor for real-time wellness insights.
• Blood oxygen (SpO2) and skin temperature tracking to spot trends early.
• Automatic sleep stage analysis: deep, light, REM, and awake time.
• Up to 7 days battery life on a single charge; full charge in 1.5 hours.
• IP68 water resistance—safe for swimming and daily submersion.
• Lightweight design (approx. 3–5 g) with hypoallergenic ceramic inner shell.
• Companion app COLMI Fit for Android and iOS.

In daily use

Slip the RING 2 onto your index or middle finger and forget it’s there. It quietly logs steps, calories, distance, and active minutes, then syncs to the COLMI Fit app for detailed graphs and trends. Vibration alerts notify you of low battery or when you hit your daily activity goal. The ring stores up to 7 days of data on-device, so you can sync at your convenience. Whether you’re an athlete tracking recovery or someone who wants a discreet health companion, the RING 2 adapts to your lifestyle.
