Ring Size & Fit Guide
A secure, comfortable fit helps the ring’s sensors maintain consistent contact with your finger. Measure the finger where you plan to wear the ring before selecting a size.
For the most reliable measurement:
- Wrap a strip of paper around the widest part of your finger.
- Mark where the two ends overlap.
- Lay the paper flat and measure the marked length.
- Compare the circumference with the size chart.
The index finger is recommended, although another finger may be used when the fit remains comfortable and secure.
Available Ring Sizes
| US Size | Inner Diameter | Finger Circumference |
|---|---|---|
| 7 | 17.3 mm / 0.68 in | 52–54 mm / 2.05–2.13 in |
| 8 | 18.1 mm / 0.71 in | 55–57 mm / 2.17–2.24 in |
| 9 | 18.9 mm / 0.74 in | 58–60 mm / 2.28–2.36 in |
| 10 | 19.8 mm / 0.78 in | 61–62 mm / 2.40–2.44 in |
| 11 | 20.6 mm / 0.81 in | 63–65 mm / 2.48–2.56 in |
| 12 | 21.4 mm / 0.84 in | 66–67 mm / 2.60–2.64 in |
| 13 | 22.2 mm / 0.87 in | 68–70 mm / 2.68–2.76 in |
Advanced Health Tracking in a Lightweight Smart Ring
The Carelders TK60 combines ECG recording with everyday wellness monitoring in a compact ring designed for continuous wear.
It tracks supported metrics including ECG, blood pressure, heart rate, blood oxygen, surface temperature, sleep and activity, then synchronizes records with the HealthWear app for easier viewing and long-term comparison.
Its stainless-steel construction, 5ATM and IP68 water resistance, multiple exercise modes and compact charging case make it suitable for both daily routines and active lifestyles.
ECG Recording Anytime, Anywhere
The built-in electrode-based ECG function allows you to record heart rhythm information directly from your finger.
The integrated contact points collect ECG signals while the ring is worn, providing a convenient way to create personal ECG records without carrying a watch or larger monitoring device.
Combined PPG and ECG Sensor Technology
The TK60 combines PPG optical sensing with a dedicated ECG chip.
PPG technology supports continuous heart rate and wellness tracking, while ECG measurement is used for individual heart rhythm recordings. Working together, the two sensing methods provide a broader view of daily cardiovascular trends.
AI-Assisted ECG Reports
ECG records can be synchronized with the HealthWear app and organized into visual reports.
The app displays waveform information and supported analysis indicators in a format that is easier to review. Previous records can also be revisited to help users compare changes over time.
ECG and AI-assisted reports are intended for personal wellness reference and should not be used as a replacement for clinical ECG testing or professional diagnosis.
Blood Pressure Monitoring
The TK60 supports finger-based blood pressure trend monitoring and stores available results in the companion app.
A measurement can be started through the connected app, while daily records help users observe how readings change over time.
Blood pressure results are estimates for wellness reference. They may be affected by ring fit, finger movement, skin contact, circulation and individual physical differences.
Continuous Heart Rate Tracking
Monitor heart rate during daily activity, rest and exercise.
The HealthWear app organizes recorded values into charts that may include recent readings, average values and daily ranges, making it easier to understand how heart rate changes throughout different activities.
Blood Oxygen Saturation Monitoring
The ring supports blood oxygen saturation monitoring and app-based record viewing.
SpO2 data can provide an additional reference point for understanding everyday wellness trends, especially when compared with heart rate, sleep and activity information collected over time.
Surface Temperature Trend Tracking
The built-in temperature sensor records changes in surface temperature and generates available reports through the connected app.
Daily records may include average, highest and lowest values, helping users notice personal temperature trends when the ring is worn consistently.
Surface temperature readings are not the same as clinical core body temperature measurements.
Sleep Monitoring and Sleep-Stage Records
Wear the TK60 while sleeping to record sleep duration and supported sleep stages.
The HealthWear app displays sleep information in visual charts, helping users compare deep sleep, light sleep and other available sleep records across different nights.
Consistent overnight wear provides a clearer picture of personal sleep routines and long-term changes.
Multiple Exercise Modes
The TK60 supports several activity modes, including:
- Running
- Cycling
- Swimming
- Mountain climbing
- Fitness
- Yoga
During supported activities, the ring records available movement and exercise information such as steps and activity duration.
Some trajectory or route information may require a connected smartphone and access to the phone’s location services.
Remote Family Health Data Viewing
The family care function allows selected health records to be shared through the HealthWear app.
After the appropriate account or family binding is completed, authorized family members can view supported data remotely, helping them stay informed even when they live far apart.
Data availability depends on app synchronization, account permissions, Bluetooth connection and internet access.
HealthWear App and Bluetooth 5.3
Connect the TK60 to the HealthWear app to view synchronized health and activity records.
The app brings supported measurements together in one location, including:
- ECG records
- Blood pressure trends
- Heart rate data
- Blood oxygen records
- Temperature trends
- Sleep analysis
- Activity history
Bluetooth Low Energy 5.3 supports efficient communication between the ring and a compatible smartphone.
Compact Magnetic Charging Case
The included charging case provides a convenient place to store and recharge the ring.
According to the product materials:
- Charging time: approximately 1 hour
- Continuous use shown in the charging image: approximately 3 days
- Standby time: approximately 7 days
The specification material separately states an estimated working time of 7–10 days. Because these figures differ within the supplied materials, actual battery performance should be expected to vary by ring size, monitoring frequency, Bluetooth use and other settings.
5ATM and IP68 Water Resistance
The TK60 is rated 5ATM and IP68 for water resistance.
It is designed to support everyday exposure to water and activities such as hand washing, bathing and swimming under appropriate conditions.
Water resistance can decrease over time due to wear, impact, temperature changes or damage. Avoid high-temperature water, saunas, diving and operating the ring beyond its stated water-resistance conditions.

Important Notes
- Health measurements are intended for everyday wellness reference and are not a substitute for professional medical equipment, diagnosis or treatment.
- ECG recordings may be affected by finger movement, dry skin, loose fit, poor electrode contact and other environmental or physical factors.
- Blood pressure, heart rate, SpO2 and temperature results may vary according to fit, circulation, skin contact and individual differences.
- For more consistent sensor contact, choose a size that feels secure without restricting circulation.
- Sleep and continuous health records require the ring to be worn for sufficient periods and synchronized with the HealthWear app.
- Remote family care requires app permissions, account binding and successful data synchronization.
- Exercise trajectory recording may rely on a connected smartphone rather than a GPS module inside the ring.
- Water resistance is not permanent and may decrease through everyday wear or physical damage.
- Battery life varies according to ring size, measurement frequency, Bluetooth connection and usage settings.
- Product interface, app appearance and available functions may change following software updates.
