Magene Multi Size Heart Rate Monitor

Newly designed hardware and algorithms help you accurately monitor your heart rate while exercising, maximising your results.

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, and choose from 3 tailored sizes for a perfect fit. The H613 heart rate monitor isn’t just a sensor - it’s your invisible coach and performance partner, guiding every step of your journey.

The H613 heart rate monitor features a new-generation self-developed heart rate algorithm. Different from traditional optical sensors that rely on indirect monitoring, it adopts proximal ECG signal direct acquisition technology - to track heart rate fluctuations in real-time. Combined with dynamic noise-reduction filtering technology, it eliminates abnormal interference signals even during high-intensity interval training or sweat-intensive cycling, enabling millimeter-level precision in heart rate tracking.

17h Offline Storage: Unrestricted Training, No Data Loss

A built-in storage chip supports 17 hours of offline recording. During outdoor cycling, mountain hiking, or gym workouts, the sensor operates independently, with no need for a phone or connected device - continuously tracking heart rate fluctuations. After your session, connect to the OnelapFit app to automatically sync and view a complete report (including workout duration, calories burned, average/max heart rate, heart rate zone distribution, etc.).

Smart Heart Rate Alert, A Safety Boundary for Every Breakthrough

The H613 heart rate monitor is equipped with a heart rate warning function that supports customizable safe heart rate thresholds. When the heart rate reaches the preset value during exercise, the sensor triggers a synchronous buzzer alert, sounding a timely "fatigue alarm" to avoid cardiopulmonary overload risks. Like an "invisible coach," the H613 heart rate monitor uses data to build the line of defense for sports safety.
