Cardiofréquencemètre Polar H1

The Polar H1 has plastic electrodes on the rear of the strap which register your heart rate. The sensor enables you to ride in a group without experiencing interference from other heart rate sensors. The Polar H1 heart rate strap can be worn during water-based activities, but sea- and pool water can cause the strap to become highly conductive, shorting the electrodes and preventing the strap from measuring the ECG signal from your heart. The soft fabric strap seamlessly forms to the natural shape of your body without impeding your movements, and the simple hook fastener allows you to quickly put on the strap and get going!
