Polar OH1 vs Polar H10 | Which is right for me?

August 30, 2017

Today we’ve announced the Polar OH1 – our first standalone optical heart rate sensor. You can get to know it in the Polar OH1 introduction post. We’ve also put together this in-depth article about optical heart rate tracking and how it works. To conclude our Polar OH1 trilogy, there’s this article right here that compares two of our latest heart rate sensors: Polar H10 and the new Polar OH1.

Let’s start by introducing our contestants. Both represent the newest heart rate tracking technology from Polar, both use Bluetooth Smart to connect to apps and Polar sports watches and both have use cases in which they really shine.

Remember: which sensor you use, which is right for you, depends on what you want to use it for. That’s why we’ll first present the tech specs side by side and then introduce some scenarios in which it makes sense to say that one works better than the other.

Ultra long sessions: Polar H10

The rechargeable battery on the Polar OH1 lasts for approximately 12 hours. The battery on the Polar H10 lasts approximately 400 hours. Some easy math reveals that for those ultra long sessions, you should choose Polar H10.

Easy to put on: Polar OH1

Polar OH1 is easy to slip on your upper or lower arm. Group fitness class about to start? Slip it on. Ready to track that grueling climb on your ride? Slip it on. Cold morning jog? You get the idea.

Orthostatic test and R-R recording: Polar H10

For advanced features which require ECG-based heart rate readings, such as the Orthostatic Test available on Polar V800, you’ll need the Polar H10.

Sports bra and heart rate: Polar OH1

If you find wearing a sports bra and a chest strap cumbersome, opt for Polar OH1.

Interval training for professional athletes: Polar H10

It’s hard to beat Polar H10 when it comes to extremely accurate heart rate measurements in a fast-paced situation, such as a hard interval training session.

Polar H10

Polar H10 uses the 5kHz frequency to transmit your heart rate in the water.

Swimming: Polar H10

If you’re into swimming or triathlon, opt for the Polar H10. It uses the 5kHz frequency to transmit your heart rate in the water. Also, you can store one session into the internal memory so you don’t necessarily need to wear a wrist unit at all.

Polar OH1

Polar OH1 is easy to use and hard to beat.

You can use Polar OH1 in the water, but it’s not optimized for tracking heart rate in the pool and you cannot use it as a sensor, only to store a swim session into the internal memory. This is because it doesn’t have the 5kHz transmission needed for sensor mode.

Heart rate sensor for fitness apps: either or both

Both Polar sensors use Bluetooth Smart to connect to your phone. Choose a sensor that fits your favorite sport – no clear winner here. Except you of course if you choose either one.
