Polar H9 Comparison Table Polar H9 Polar H10 Polar Verity Sense Polar OH1+ Review: The Gold Standard - This review is for the Polar H9 Heart Rate Monitor (HRM) in Black. I purchased the HRM to prep for a Half Marathon, my first ever, with the hope of using it for Low Heart Rate training. It has been an excellent choice for a beginner like me and has helped accurately track my heart rate during runs. This has helped me improve my runs over the 2 months I've used it so far. Build and Quality: The HRM unit and the strap come packaged as separate items. The HRM unit is compact and lightweight, made from a durable plastic and the quality feels solid. Just holding it in your hands you can tell that the plastic is strong enough to withstand any bumps, etc. It houses a CR2025 battery that you can get to using a prying tool. The 'Soft Strap' is just that, a strap with a fine-weave and feels velvet-feel to the touch. The quality seems good and like anything elastic its durability will depend on how much it is stretched. It is adjustable and is fastened using a hook into a loop and the HRM unit and strap are connected together with a pair of snap fastener buttons. Features vs Functionality: Polar HRMs are known for their accuracy and I can confirm this sensor is spot on. The H9 is accurate and also very responsive to changes in the heart rate with minimal lag. Where my Garmin wrist sensor would lag before reacting to heart rate changes, the H9 was pretty much instant. Although, for the strap to measure heart rate accurately, the conducting area on the strap needs to be made wet before use to begin with and the sweat then keeps it wet for the rest of the workout The strap is made from a comfortable and flexible material and sits snugly against the skin once adjusted appropriately. I've not had any chaffing and on tuns I don'teven realise I have the chest strap on. I don't particularly sweat too much so all I do it wipe the strap down after use and its good to go for the next workout. For sweaty runners, you may need to wash it more often which might impact its longevity. As for connectivity, the HRM is easy to connect to Bluetooth devices and once paired will automatically connect the next time as long as the HRM is snapped to the strap. I've also tested connecting two devices and both recieve the heart rates in real time. However, if you ever need to let your running partner to use the HRM then you'd want to unpair this from your fitness tracker first before they connect to it. Else it would send their heart rate to your tracker. The claimed battery life of 400 hours is great but difficult to verify. So what I do to ensure the battery lasts is to unsnap one of the button from the strap to break the circuit. Value for money: The H9 provides accurate heart rate data for a fraction of the price of the H10 as long as you don't need the memory of the H10. This as brilliant value for money, specially for beginners. Review: Works - I use this to connect to my garmin watch and bike computer and it connects flawlessly. Only thing I would say is don’t use the cheap batteries you get on the pound shelf, they will last very little time. With quality batteries I get a massive amount more use without having to g to replace it. ## Features - POLAR presents a new affordable HRM when you're looking for a reliable high quality heart rate monitor for your everyday sports Polar H9 is a trusted choice of HR sensor that fulfills all your needs - Gold standard in heart rate tracking built on decades of scientific research and development recognised by both regular users and researchers around the globe Polar is proud to be the Gold Standard in HR tracking - CONNECTIVITY OPTIONS: Polar H9 connects to sports and smart watches (Polar Garmin) activity trackers gym equipment and other bluetooth and ANT+ devices - Now your cardio workouts are more effective: From gym to indoor cycling via jogging and group exercise, track your heart rate and get an accurate calorie burn - Turn your phone into fitness tracker: Enjoy endless connection possibilities to Polar beat, Polar club, peloton, Nike+ run club and other popular fitness and training apps ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08411CZYL | | Battery Description | CR2025 Lithium Coin Battery | | Best Sellers Rank | 2,174 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 6 in Heart Rate Monitors (Sports & Outdoors) | | Brand | Polar | | Brand Name | Polar | | Colour | Black | | Compatible Devices | Smartphones | | Compatible devices | Smartphones | | Country Of Origin | Malaysia | | Customer Reviews | 4.2 out of 5 stars 9,835 Reviews | | Display Size | 0.96 Inches | | Included Components | Heart rate sensor, soft strap | | Item Dimensions L x W x H | 34L x 65W x 10H millimetres | | Item Type Name | Bluetooth - Waterproof HR Monitor with Soft Chest Strap | | Item Weight | 60 Grams | | Manufacturer | Polar | | Manufacturer Part Number | 92081566 | | Material | Plastic | | Material Type | Plastic | | Model Number | H9 | | Product Warranty | 2 year manufacturer | | Product dimensions | 34L x 65W x 10H millimetres | | Screen size | 0.96 Inches | | Sensor Type | PPG | | Size | XS-S | | Team Name | Polar | | UPC | 725882053936 | ## Product Details - **Battery description:** CR2025 Lithium Coin Battery - **Brand:** Polar - **Colour:** Black - **Compatible devices:** Smartphones - **Item weight:** 60 Grams - **Material:** Plastic - **Product dimensions:** 34L x 65W x 10H millimetres - **Screen size:** 0.96 Inches - **Sensor type:** PPG - **UPC:** 725882053936 ## Images ![Polar H9 - Image 1](https://m.media-amazon.com/images/I/51LhhgJ+1lL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Questions & Answers **Q: Why won’t my Polar H9 pair with my device?** A: If you're experiencing pairing issues, ensure you have fastened the strap around your chest and connector is attached.
