Introducing the Polar OH1 optical heart rate sensor. Optimized for use on the lower or upper arm, Polar OH1 provides an alternative method for measuring your heart rate during training. It tracks your heart rate with Polar’s high-quality 6-LED optical heart rate solution. The comfortable textile armband is easy to put on anytime, anywhere and fits snugly, comfortably and discreetly around your arm.
Compatible with the entire Polar family, and a whole host of 3rd party apps, Polar OH1 may also be used as a standalone heart rate sensor thanks to its Bluetooth connectivity and built-in memory that can store up to 200 hours of training data. After your session, you can sync your data to Polar Flow with both the Polar Flow app and web service.
