Polar Power Output Sensor Set

The Polar Power Output Sensor, contains different measuring aspects that inform how the cyclist works with the bike and enables the cyclist to control the intensity of exercise. The Polar Power Output Sensor gives all information in one device only. It combines heart rate monitoring and power output measurement.

Together with the Polar S625X or Polar S725, the Power Output Sensor measures the actual, average and maximum power values. With the Power Output Sensor you can analyze the L/R Balance(balance between left and right foot) and Pedaling Index (shows how even the power is distributed during one crankarm rotation). The Power Output Sensor also measures cycling speed, distance and cadence. You can easily download the data to the Polar Software for further analysis.

All of the drive force of the bike is transmitted through the chain, allowing the Polar Power Output Sensor to calculate power accurately. The sensor positioned on the rear pulley works magnetically and measures the speed of the chain. The chain stay sensor (power sensor) calculates the tension of the chain by measuring the vibration as the chain passes over the sensor. The Polar Power Output Sensor also has built-in cadence and speed sensors. The information is then transmitted to the heart rate monitor, which is mounted to a bracket on the handlebars.
