Before taking a new sensor into use, it has to be paired with your watch. Pairing only takes a few seconds, and ensures that your watch receives signals from your sensors only, and allows disturbance-free training in a group. Before entering an event or race, make sure that you do the pairing at home to prevent interference due to data transmission. For instructions, see Pairing sensors with your watch.

Polar OH1 optical heart rate sensor

Polar OH1 is a compact optical heart rate sensor that measures heart rate from your arm or temple. It's versatile and offers a great option to heart rate chest straps and wrist-based heart rate devices. With Polar OH1 you can broadcast your real-time heart rate to your sports watch, smart watch or Polar Beat or other fitness app via Bluetooth, and simultaneously to ANT+ devices. Polar OH1 has an inbuilt memory so you can start your workout with OH1 alone and transfer the training data to your phone afterwards. It comes with a comfortable machine-washable armband and a swimming goggle strap clip (in Polar OH1 + product package).

It can also be used with Polar Club, Polar GoFit and Polar Team app.

Polar H10 heart rate sensor

Monitor your heart rate with maximum precision with the Polar H10 heart rate sensor with a chest strap.

Although the Polar Precision Prime is the most accurate optical heart rate measurement technology there is and works pretty much anywhere, in sports where it's more challenging to keep the sensor stationary on your wrist or where you have pressure or movement in muscles or tendons near the sensor, the Polar 10 heart rate sensor gives you the best heart rate accuracy. The Polar H10 heart rate sensor is more responsive to rapidly increasing or decreasing heart rate, so it’s the ideal option also for interval type of training with quick sprints.

The Polar H10 heart rate sensor has an internal memory that allows you to record one training session with it without a connected training device or a mobile training app close by. You just need to pair the H10 heart rate sensor with the Polar Beat app and start the training session with the app. This way, you can for example record your heart rate from your swimming sessions with the Polar H10 heart rate sensor. For more information see the support pages for Polar Beat and Polar H10 heart rate sensor.

When using the Polar H10 heart rate sensor during your cycling sessions, you can have your watch mounted to your bike’s handlebars to easily view your training data while riding.

Polar H9 heart rate sensor

Polar H9 is a high quality heart rate sensor for your everyday sports. It comes with the Polar Soft Strap and tracks your heart rate accurately. Polar H9 is ideal with the Polar Beat app as well as many 3rd party apps: you can turn your phone into a fitness tracker easily. Further, Bluetooth®, ANT+™ and 5 kHz technologies ensure connections to a large variety of sports devices and gym equipment. Thanks to chest strap measurement Polar H9 reacts instantaneously to what happens in your body and gives you accurate calorie burn.
