Polar H10 Heart Rate Sensor

The Polar H10 is the most accurate wearable heart rate sensor available, verified in independent clinical studies to be within 1 BPM of ECG measurement at all exercise intensities. Medical-grade textile electrodes detect electrical heart signals rather than light — the same principle as a hospital ECG — providing data that optical wrist sensors cannot match during high-intensity exercise. Compatible with all major sports devices via Bluetooth and ANT+.

• ECG-level accuracy — verified within 1 BPM
• Medical-grade textile electrode — superior to optical sensors
• Bluetooth and ANT+ dual connectivity
• Internal memory — records one session without device
