Track heart rate with millimeter accuracy, stay protected by intelligent alerts, and train strategically with 5-color zone indicators. Seamlessly connect three devices via 3-channel Bluetooth. The H613 heart rate monitor isn’t just a sensor—it’s your invisible coach and performance partner, guiding every step of your journey.

Features
Versatile Sport Compatibility・Precision from Every Angle: The H613 heart rate monitor is suitable for multiple sports scenarios, supporting various types of exercise including high-intensity intervals (boxing, spinning), endurance training (cycling, hiking), static control (yoga, Pilates), and strength training.
Heart Rate Alerts for Safer Training: Equipped with a customizable heart rate warning function, the H613 allows users to set safe heart rate thresholds. When the preset limit is reached, the built-in buzzer triggers an immediate alert—a “fatigue alarm” that helps prevent cardiopulmonary overload. Acting like an invisible coach, the H613 heart rate monitor uses data to safeguard your training intensity.
Connect Three Devices, Share Data Seamlessly: Supporting both ANT+ and Bluetooth protocols, the H613 allows simultaneous data recording across multiple platforms with stable transmission. The Bluetooth channel can connect to up to three devices at once—such as a sports app, smartwatch, and treadmill—without the need for manual switching or data transfer, ensuring uninterrupted heart rate sharing during workouts.
Anti-Bacterial, Anti-Odor & Anti-Slip: Move Freely, Sweat Fearlessly: The H613 features antibacterial and deodorizing technology to inhibit microorganisms and maintain freshness. Its chest strap is embedded with non-slip silicone to reduce movement during high-intensity or prolonged sessions, minimizing skin irritation from over-tightening. A stable fit ensures both comfort and accurate data tracking.
