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. \u003c\/p\u003e\u003cp\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 millimeter-level precision in heart rate tracking.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e17h Offline Storage: Unrestricted Training, No Data Loss\u003c\/strong\u003e\u003c\/p\u003e\u003cp\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\/p\u003e\u003cp\u003e\u003cstrong\u003eSmart Heart Rate Alert, A Safety Boundary for Every Breakthrough\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\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 simulatneous 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\u003c\/ul\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-device wireless connectivity:\u003c\/strong\u003e Supports ANT+ and bluetooth to share heart rate data with up to 3 devices simultaneously\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnti-bacterial, anti-odour, and anti-slip design: \u003c\/strong\u003eKeeps the strap fresh and secure during intense or long workouts while ensuring stable, accurate heart-rate tracking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eErgonomic curved design: \u003c\/strong\u003e10.8 - 8mm curved design conforms to the chest for millimetere level dynamic tracking and friction free movement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIPX7 waterproof rating:\u003c\/strong\u003e Suitable for intense training sessions, rain, and sweat‑heavy workouts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExceptional battery life: \u003c\/strong\u003eUp to 100 hours of use from a rechargeable lithium battery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-size fit:\u003c\/strong\u003e Three size options ensure accurate, comfortable support for athletes of all body types.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Magene","offers":[{"title":"Long Strap 90-136cm","offer_id":44167986839732,"sku":"MA30103L","price":49.0,"currency_code":"GBP","in_stock":true},{"title":"Medium Strap 75-100cm","offer_id":44167986872500,"sku":"MA30103M","price":49.0,"currency_code":"GBP","in_stock":true},{"title":"Short Strap 58-78cm","offer_id":44167986905268,"sku":"MA30103S","price":49.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0669\/2539\/6148\/files\/ma30103l.jpg?v=1774369021","url":"https:\/\/www.99bikes.co.uk\/products\/magene-multi-size-heart-rate-monitor","provider":"99 Bikes UK","version":"1.0","type":"link"}
