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.
