Polar OH1 Optical Heart Rate Sensor


The Polar OH1 is an optical heart rate monitor armband that combines versatility, comfort and simplicity. It fits comfortably around your arm and tracks heart rate with Polar’s high-quality optical heart rate solution. This is a nice alternative to the typical heart rate monitor strap which is normally worn around the chest; if you’re not a fan of those then choose the OH1 instead which works with all Bluetooth-compatible Polar sports watches, trackers and cycling computers. 

The Polar OH1 can also be used with your smartphone via an app, the OH1 streams real-time heart rate to many popular fitness apps on both iOS and Android phones. Polar OH1 is also a great companion to Polar Beat, Polar’s free fitness and training app. With Polar OH1 and Polar Beat you can access live heart rate data right on the screen of your phone and audio guidance to your headphones during your ride. If you prefer to train without a watch or phone the Polar OH1 features an internal memory that can store up to 200 hours of training data.
