The H613 heart rate monitor isn’t just a sensor - it’s your invisible coach and performance partner, guiding every step of your journey. \u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe 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 millimetre-level precision in heart rate tracking.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e17h Offline Storage: Unrestricted Training, No Data Loss\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eA 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.).\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eSmart Heart Rate Alert, A Safety Boundary for Every Breakthrough\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe H613 heart rate monitor is equipped with a heart rate warning function that supports customisable 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 defence for sports safety.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 61.1x28.9x10.8mm\u003c\/li\u003e\n\u003cli\u003eChest strap lengths: Short (58-78cm) \/ Medium (75-100cm) \/ Long (93-136cm)\u003c\/li\u003e\n\u003cli\u003eWaterproof grade: IPX7\u003c\/li\u003e\n\u003cli\u003eWireless protocol: Bluetooth (up to 3 simultaneous connections), ANT+\u003c\/li\u003e\n\u003cli\u003eWeight: 12.4g (sensor only)\u003c\/li\u003e\n\u003cli\u003eBattery type: Rechargeable lithium battery\u003c\/li\u003e\n\u003cli\u003eCharging method: Magnetic charging\u003c\/li\u003e\n\u003cli\u003eMulti-device wireless connectivity: Supports ANT+ and Bluetooth to share heart rate data with up to 3 devices simultaneously\u003c\/li\u003e\n\u003cli\u003eAnti-bacterial, anti-odour, and anti-slip design: Keeps the strap fresh and secure during intense or long workouts while ensuring stable, accurate heart-rate tracking.\u003c\/li\u003e\n\u003cli\u003eErgonomic curved design: 10.8 - 8mm curved design conforms to the chest for millimetre-level dynamic tracking and friction-free movement\u003c\/li\u003e\n\u003cli\u003eIPX7 waterproof rating: Suitable for intense training sessions, rain, and sweat‑heavy workouts\u003c\/li\u003e\n\u003cli\u003eExceptional battery life: Up to 100 hours of use from a rechargeable lithium battery\u003c\/li\u003e\n\u003cli\u003eMulti-size fit: Three size options ensure accurate, comfortable support for athletes of all body types.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Magene","offers":[{"title":"58-78cm","offer_id":62754726478211,"sku":"CM30103S \/ B38 K4 MIXED BOX 1","price":49.99,"currency_code":"GBP","in_stock":true},{"title":"75-100cm","offer_id":62754726510979,"sku":"CM30103M \/ B38 K4 MIXED BOX 1","price":49.99,"currency_code":"GBP","in_stock":true},{"title":"90-136cm","offer_id":62754726543747,"sku":"CM30103L \/ B37 Q5 MIXED BOX 2","price":49.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0582\/0196\/4698\/files\/57_de7806d6-12f3-4e60-be14-6e053a17ba23.jpg?v=1791297974","url":"https:\/\/sportandleisure.com\/products\/magene-h613-heart-rate-monitor","provider":"Sport \u0026 Leisure","version":"1.0","type":"link"}
