Zephyr™ HxM


Product currently not available!


With the Zephyr™ HxM, there is finally a powerful heart rate sensor on the market which can connect to almost all Smartphones via Bluetooth™. New Zealand based Zephyr Technologies is a specialist for biometric sensors that has, until now, been selling professional products only.

The Zephyr™ HxM stands out due to its being comfortable to wear (very light, textile strap), its long battery life and its measuring accuracy. In addition to the heart rate data, the device also gathers acceleration data which can, for instance, be used to calculate your cadence (when running or walking).


The Zephyr™ HxM is the ideal complement for the Run.GPS sports software. Run.GPS is able to use all data sent by the HxM and relate it to the training data coming from other sources. If the GPS signal is bad or not available, Run.GPS will use the HxM data as a substitute for the missing distance and speed data.

The device can be used with all versions of Windows Mobile or with Google Android 2.0 (or higher). It's not possible to use it with Google Android 1.x.

  • very light-weight
  • powerful lithium ion battery guarantees long battery life (about 26 hours)
  • comfortable textile strap

Hints for operating your HxM

  • As with most heart rate straps, the HxM is activated by putting it on. If you have dry skin, you must dampen the textile strap under a faucet before wearing it (the contacts need to get damp to have optimal electrical contact with your skin).
