Frequently Asked Questions
Everything you need to know about Polar H9.
How does Polar H9 measure heart rate?
Polar H9 uses electrical heart rate measurement through electrodes in its chest strap. This technology provides accurate heart rate readings during a wide range of training activities.
Can I use Polar H9 with my smartphone?
Yes. Polar H9 connects to compatible smartphones using Bluetooth Low Energy. You can use Polar Flow, Polar Beat or other compatible applications to monitor and record your training.
Does Polar H9 work with sports watches?
Yes. Polar H9 is compatible with sports watches that support standard Bluetooth or ANT+ heart rate sensors, including compatible Polar watches and selected devices from other manufacturers.
Does Polar H9 support Bluetooth and ANT+?
Yes. Polar H9 supports Bluetooth Low Energy, ANT+ and Polar GymLink 5 kHz connectivity. It can transmit heart rate data through Bluetooth and ANT+ simultaneously.
Can Polar H9 connect to two Bluetooth devices at once?
No. Polar H9 does not support two simultaneous Bluetooth connections. Polar H10 offers this feature if you need to connect to two compatible Bluetooth devices at the same time.
Can Polar H9 record a workout without a phone or watch?
Polar H9 does not have built-in training memory. To record a workout, use a compatible receiving device or training application.
Can I use Polar H9 while swimming?
Polar H9 is water-resistant to 30 metres. Polar GymLink 5 kHz transmission can be used with compatible devices in water, but Bluetooth and ANT+ signals do not transmit effectively underwater.
How long does the Polar H9 battery last?
Polar H9 offers up to 400 hours of operating time with a replaceable CR2025 battery. Actual battery life depends on usage.
How do I pair Polar H9 with Polar Flow?
Moisten the electrode areas of the strap, fasten it securely around your chest and attach the sensor. Open Polar Flow, sign in to your account and follow the sensor pairing instructions in the application.
Pair the sensor directly through Polar Flow rather than your phone's Bluetooth settings.
What is the difference between Polar H9 and H10?
Both sensors use electrical heart rate measurement and support Bluetooth, ANT+ and GymLink connectivity.
Polar H10 adds internal memory for one training session, dual Bluetooth connectivity and the Polar Pro Strap. Polar H9 uses the Polar Soft Strap and offers essential heart rate monitoring at a lower price.
