Key specifications

• ECG-accurate heart rate measurement with Polar Pro soft strap (M-XXL, 65–95 cm)
• Dual Bluetooth and ANT+ connectivity, plus 5 kHz transmission for gym equipment
• Waterproof to 30 m (WR30) – swim, run in rain, or sweat without worry

Why choose it

The Polar H10 is widely regarded as the gold standard in heart rate monitoring, trusted by professional athletes and coaches for its ECG-level precision. Unlike optical wrist sensors, the chest strap measures electrical signals directly from your heart, eliminating motion artifacts and lag. The soft, adjustable Pro strap stays comfortable during long sessions, while the sensor's robust design withstands sweat, rain, and pool water. With dual Bluetooth connections, you can simultaneously connect to a watch and a fitness app, and the built-in memory lets you train without a device and sync later.

Ideal use cases

• Running and cycling with real-time heart rate zones on your watch or app
• Swimming workouts with waterproof performance and offline recording
• Gym sessions paired with compatible cardio machines via 5 kHz or ANT+
• HIIT and interval training where precise heart rate response is critical

Good to know

The H10 sensor is compatible with Polar Flow, Strava, Nike Run Club, and many other fitness apps. The Pro strap is machine washable (detach sensor first) and made from breathable materials to reduce chafing. For best accuracy, moisten the electrode areas before wearing. The sensor's operating temperature range is -10 °C to +50 °C, making it suitable for most outdoor conditions. Firmware updates via the Polar Flow app ensure you always have the latest features and improvements.
