Polar H10 Heart Rate Sensor with Chest Strap – Bluetooth/ANT+/5 kHz, Black, M-XXL

The Polar H10 redefines precision in heart rate monitoring by capturing the heart's electrical signals directly at the source. Unlike optical wrist sensors that can lag or lose accuracy during intense movement, the H10 delivers medical-grade ECG data even in the most demanding conditions—sprints, intervals, or swimming. With simultaneous dual Bluetooth connections, ANT+ and 5 kHz compatibility, and onboard memory, it is the most versatile chest strap sensor Polar has ever produced, trusted by professional athletes and coaches worldwide.

Highlights

• Medical-grade ECG-accurate heart rate measurement
• Simultaneous dual Bluetooth Low Energy connections – broadcast to two devices at once
• ANT+ and 5 kHz (GymLink) compatibility for gym equipment and sports watches
• Water-resistant to 30 meters – suitable for swimming and water sports
• User-replaceable CR 2025 battery with up to 400 hours of operation
• Built-in memory for one training session (up to 65 hours) – train without your phone
• Soft textile strap with silicone dots and stainless steel buckle for a secure, comfortable fit

In daily use

Slip on the adjustable strap (fits chest circumference 65–95 cm, size M-XXL) and position the sensor just below your chest. The sensor is lightweight (21 g) and the strap is breathable, making it comfortable for long training sessions. The Bluetooth range of up to 10 meters lets you move freely while your data streams to your smartphone or sports watch. After a workout, the sensor stores your session internally, so you can sync it later with the Polar Flow app or other compatible platforms.
