Polar H1 Heart Rate Sensor Review

Polar H1 is Stylish, slim and very comfortable. It comes along with Chest Strap. It is a sensor and not a monitor. Thus, It doesn’t include the Wrist Watch. Most of the polar heart rate “monitors” come with H1 heart rate sensor.

  • Accuracy

    The H1 heart rate sensor is proven to be accurate. It transmits data in coded 5kz tranmission form. Thus, avoiding any interference from other devices.

  • Ease of Use

    It has a chest strap, that takes shape of your body. You don’t feel that you are wearing one. The material is soft like cloth. It comes in two sizes M-XXL and XS-S.

  • Combatibility

    As mentioned earlier, most of Polar products used H1 sensor. Hence it is compatible with models such as FT1, FT2, FT4, FT7, FT40, FT60, FT80 and Polar Loop. You can view the reading in any of the compatible wrist watch.

    It has GymLink technology transmission, hence it is compatible with all gym equipment. You can as well view your reading on gym equipments.

    H1 doesn’t support data transfer using Bluetooth.

  • Additional Features

    • Water Resistance: Since H1 heart rate sensor uses GymLink, it can transmit data under water too. So good choice for swimmers.
    • Battery: It has user replaceable Lithium batteries.



Except Bluetooth functionality, H1 heart rate sensor is well equipped and a good product to buy. It comes as default sensor for many Polar heart rate monitors. In case you want to look your results in mobile app or smart phones then better check Polar H7 (supports both GymLink and Bluetooth) or H6 (Supports Bluetooth).

    I have a Polar H1 Sensor and a FT7 accompanying watch. Recently. after running up a short hill, the watch heart-rate numbers jumped up considerably to up to 155 and then back down, and up and down and up and down, continuously, even though I had stopped running and just walked at a brisk pace to cool off for seceral more minutes. Should I ask my Doctor about this sudden extremely high readings? Or is it that the sensor has wron out and needs replacing?

    Many thanks for your help.

      I have warn heart rate monitors for years and they do act up. The best bet is to use an electrode gel such as ba-bump. The numbers you are seeing I believe may be error codes for a bad transmission. If you are concerned about medical issues, take your heart rate manually, but 99.9% of the time it is the monitor failing to make good skin contact.

    The sensor stops working after a few months. Apparently this is common. I changed the battery, and it still won’t read.
