Magene H613 Heart Rate Monitor

New Algorithm Upgrade, Precise Heart Rate Tracking

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. Every heartbeat becomes reliable data for scientific training.

*This heart rate sensor is for sports use only and cannot replace medical devices.

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, and more). Stay focused on training while seamlessly managing your data—no device dependency required.

Versatile Sport Compatibility — Precision from Every Angle: The H613 supports high-intensity intervals (boxing/spinning), endurance training (cycling/hiking), static control (yoga/Pilates), and strength training.

Smart Heart Rate Alert: A Safety Boundary for Every Breakthrough

The H613 is equipped with a customisable heart rate warning function. When your heart rate reaches the preset threshold during exercise, the sensor triggers a synchronous buzzer alert—a timely "fatigue alarm" to avoid cardiopulmonary overload risks. Like an invisible coach, the H613 uses data to build your line of defence for sports safety.

*Heart rate warning values are set in the OnelapFit app.

Connect Three Devices, Share Data Seamlessly

The H613 supports ANT+ and Bluetooth standard protocols simultaneously. The Bluetooth channel supports up to 3 devices connected at once—eliminating manual device switching or data fragmentation. For example, the H613 can connect to a sports app, smartwatch, and treadmill simultaneously during gym workouts.

Anti-bacterial, Anti-odor & Anti-slip: Move Freely, Sweat Fearlessly

The H613 adopts antibacterial and deodorizing technology, effectively inhibiting microorganisms to maintain long-lasting freshness. The chest strap is embedded with non-slip silicone that reduces displacement during high-intensity workouts and long-term wear, minimising the risk of abrasions caused by over-tightening.

Deodorizing Performance: Eliminates 93.7% of ammonia, 89.4% of acetic acid, 95.2% of isovaleric acid, and 99.3% of 2-nonenal. *Tested according to ISO-17299.

Bacterial Inhibition Rate: Inhibits 94.35% of Candida albicans, 99.13% of Escherichia coli, 99.55% of Staphylococcus aureus. *Tested according to ISO-20743.

Crafted Design For Comfort And Durability

The ergonomic 10.8mm-to-8mm curved design precisely conforms to the chest for millimeter-level dynamic tracking—whether during running arm swings, cycling bends, or powerlifting shoulder presses.

The sealed battery compartment achieves IPX7 waterproofing, withstanding rain during outdoor training and intense sweating in the gym. Weighing just 12.4g, the ultra-light body offers zero-pressure wear with high scratch and wear resistance.

Multi-Size Fit — Sport Shouldn't Be Defined by Size

Available in Medium (75–100cm) and Large (93–136cm) to suit a wide range of body types—from teenagers to larger athletes. Measure your chest circumference and choose the size that falls within your range.

Frequently Asked Questions

What is the difference between ECG and optical heart rate monitoring?

ECG chest straps measure electrical heart signals directly; optical wrist monitors use light to detect blood flow — ECG is significantly more accurate for high-intensity sport. ECG monitors like the H613 place electrodes against your skin to capture the heart's electrical impulses beat-by-beat, even during sprints and rapid heart rate changes. Optical (PPG) monitors use light to detect blood flow changes at the wrist, which can lag or lose accuracy during intense exercise, cold conditions, or device movement. For athletes training in heart rate zones, a chest strap ECG monitor is the gold standard.

Is a chest strap heart rate monitor more accurate than a wrist-based one?

Yes, for most sport applications. Chest strap ECG monitors like the H613 measure electrical heart signals directly, giving real-time beat-to-beat accuracy. Wrist-based optical monitors can be affected by movement, skin tone, and sweat, particularly during high-intensity efforts. Studies consistently show chest straps outperform optical wrist monitors for interval training and cycling.

What heart rate zones does the Magene H613 use?

The H613 uses five heart rate zones, indicated by the LED light on the sensor during exercise: White (Warm-up), Blue (Fat burning), Green (Aerobic endurance), Yellow (Threshold), and Red (Anaerobic endurance). Zone thresholds are based on your heart rate data and can be monitored in real time on a paired bike computer or in the OnelapFit app. The sensor flashes the corresponding colour during your workout so you can see your zone at a glance without looking at a screen.
