Heart Rate Sensors: Polar Verity Sense vs Polar H10 and Polar H9 (2024)

As far as heart rate sensors are concerned, Polar offers a solid trio for any heart rate tracking need: Polar Verity Sense vs Polar H10 and Polar H9.

All three are equipped with Polar’s innovative heart rate tracking technology. All three use Bluetooth® and ANT+ to connect to a great variety of training devices, apps, and Polar sports watches. All three have specific use cases in which they really shine.

But how do you know which heart rate sensor is right for you?

Let’s start at the highest level. One important factor that differentiates Polar Verity Sense vs. Polar H10 and Polar H9 is that Polar H10 and H9 are worn on the chest with a chest strap, whereas Polar Verity Sense is an optical heart rate sensor that can be worn on your arm, clipped to your swimming goggles, or placed just about anywhere on your body where it can fit snugly against your skin.

While both chest strap and optical sensors measure your heart rate, they do it in different ways, using different technologies.

The chest strap measures the electrical activity of the heart, and it’s recognized as the most precise way to measure heart rate. The optical heart rate sensor measures changes in the size of blood vessels with the help of LED lights and a light detector – ultimately providing incredibly accurate heart rate readings effectively.

Another practical thing is that the electrodes on the chest strap need moisture to work, meaning that you must have some water handy to get the chest strap sensor to function. The optical heart rate sensor doesn’t need any moistening so you can start training quicker and easier.

It may sound boring, but if you want all the information quickly in one glance, check out the feature comparison table.

For now, let’s explore all sensors deeper with the help of some basic use cases:
