Intelligent design

Don’t you love when things do exactly what they were designed to do? Polar H10 was designed to accurately measure your heart rate. And that’s exactly what it does.

Firm Buckle

This ensures close contact against your skin to block out any motion interference when you move.

Non-Slip Silicone Spots

These keep the sensor gripped to your chest at all times so it can measure your heart rate optimally.

Soft Textile Strap

This provides maximum comfort whenever you wear the sensor, for as long as you wear it.

The Science of Perfection

Measuring heart rate correctly is easy, but measuring heart rate correctly when you’re engaged in high-intensity exercise is not. This is where the Polar H10 ECG heart rate monitor excels.


Electrocardiogram (Polar H10)


Optical Heart Rate (Sports Watches)

It's well connected

You can record a training session, connect to your smartphone, broadcast to a huge range of gym equipment, and sync to your favorite fitness and sports apps. Oh, and you can even use it with products from other brands.

One device. Multi-sports.

Maybe you want more accuracy. Maybe you don’t want distractions. Or maybe you just don’t want to wear a watch (or a fancy piece of jewellery on your finger) when you train.

Chest strap monitors are ideal for any sport – and with Polar Flow, you can choose from over 150 of them.

How to take care of your Polar H10

Want to maximize the life span of your sensor? These simple tips will ensure you get the most reliable heart rate measurement for longer.


How do electrical (ECG) sensors like Polar H10 differ from optical sensors like Polar Verity Sense?

Polar H10 and Polar Verity Sense use different types of technology to monitor heart rate, and each has its unique advantages and applications.

Polar H10 (ECG Sensor):
  • Technology: Polar H10 uses electrical sensors (ECG or electrocardiogram technology). It measures the electrical activity generated by the heart muscle when it contracts. This sensor requires direct skin contact and is typically worn around the chest with a chest strap.
  • Accuracy: ECG sensors are considered the gold standard for heart rate monitoring, particularly when precise heart rate measurement is crucial, such as in medical or high-performance sports settings.
  • Use Case: Ideal for continuous monitoring during intense physical activities and sports where accurate, real-time heart rate data is critical.
Polar Verity Sense (Optical Sensor):
  • Technology: Polar Verity Sense uses optical heart rate technology, which involves shining a light into the skin and measuring the light absorption changes caused by blood flow. This sensor can be worn on the upper arm or forearm.
  • Accuracy: While optical sensors are highly accurate, they can sometimes be affected by factors like movement and changes in ambient light, making them slightly less reliable than ECG sensors under certain conditions.
  • Use Case: Optical sensors are more versatile for everyday use and are suitable for a wide range of activities, offering a good balance between convenience and accuracy.

Both devices cater to different needs based on the activity and the level of detail required in heart rate monitoring. The choice between an ECG sensor like Polar H10 and an optical sensor like Polar Verity Sense often depends on the specific requirements of your activities and personal preference for where and how you like to wear your heart rate monitor.

What is the battery life of Polar H10 Heart Rate Sensor, and is it rechargeable?

Polar H10 Heart Rate Sensor uses a CR2025 battery, which is not rechargeable. It has a battery life of approximately 400 hours of use, which is quite long-lasting given its application. When the battery does run low, it's easy to replace it with a new CR2025 coin cell battery.

For more details on battery replacement:

Can Polar H10 be used together with a sports watch?

Yes, Polar H10 heart rate sensor can be used together with a sports watch, making it a versatile choice for athletes who want to track their heart rate accurately during workouts. Polar H10 is compatible with many sports watches that support Bluetooth and ANT+ connectivity, including Polar sports watches and other brands.

Here are some steps to connect your Polar H10 to a sports watch:
  1. Wear the H10 heart rate sensor around your chest, directly against your skin and moisten the electrode area.
  2. Put your sports watch in pairing mode. This usually involves going to the settings menu and selecting the option to add a new device or heart rate sensor.
  3. Select Polar H10 from the list of available devices on your sports watch.

Once paired, your sports watch should receive heart rate data directly from Polar H10 during your training sessions.

For more information about how to use Polar Flow with your Polar H10, you can refer to the following Polar support articles:

What is ECG?

An ECG–or Electrocardiogram–is a visual representation of the electric signals originating from the heart.

As your heart beats, the electric signals transmit through the fluids in your body onto your skin – where you can place electrodes to measure the changes.

The best place to take such measurements is the chest because it’s closest to the heart – hence chest strap heart rate monitors like Polar H10.

What is OHR?

OHR–or Optical Heart Rate–measures, interprets, and uses PPG signals to calculate your heart rate.

PPG stands for photoplethysmogram, or photoplethysmography, which means optically measuring the volumetric changes of an organ.

In short: OHR technology uses LEDs and a photodiode to measure the changes in the size of blood vessels under your skin – making it the ideal solution for wrist devices like Polar Watches.

ECG vs. OHR: which is better?

Well, that depends on your needs.

OHR is the technology we use in our sports watches to measure heart rate from the wrist. If you value style, usability, comfort, and convenience, and you want to see your live status displayed as you train, as well as 24/7 activity tracking and sleep monitoring, then sports watches are the best choice for you.

But if you want to engage in high-intensity training or performance situations that require extreme motion from your arms (racket sports), and need more accurate measurement that responds quickly to rapidly increasing heart rate (interval training / sprints) without being affected by temperature, water, sweat, or even skin pigmentation, then an ECG chest strap sensor such as Polar H10 ticks all the boxes.
