POLAR H10 Heart Rate Sensor Bluetooth XS-S Black

The Polar H10 Heart Rate Sensor Bluetooth XS-S Black is a chest-worn heart rate monitor designed for continuous data tracking during sport and exercise. It transmits metrics to compatible sports watches, phones, and gym equipment using dual Bluetooth 4.0 and ANT+ connectivity, which makes it suitable for activities such as running, swimming, and interval training. A defining feature is its internal memory, which records training sessions independently without a connected receiver. The device is powered by a CR2025 coin-cell battery that provides up to 400 hours of operational life.

The strap has a Polar Pro textile construction with integrated silicone elements to keep it from shifting. Its water-resistant build tolerates submersion for swimming and allows the textile strap to be washed after use. Firmware and software updates are delivered wirelessly, and compatibility extends across iOS and Android platforms, integrating with fitness apps such as Polar Beat as well as gym equipment ecosystems. The adjustable strap provides a secure fit tailored for the XS-S size range.
