| The heart generates an electrical signal that can be measured on skin. The
transmitter contains two electrodes to detect the electrical signal on your skin. The
electrodes are mounted on a sealed transmitter that is attached to the chest with elastic
belt. The transmitter detects the voltage differential on the skin during every heart beat
and sends the signal continuously and wirelessly using an electromagnetic field to the
wrist receiver. This method is based on ultra low power consumption, which is guaranteed
with the unique insertion moulded electronics module and carefully designed and tested
circuitry to pick up the electrical signal of the heart. Polar´s unique patented
one-piece molded construction makes the Polar chest transmitter the only 100% waterproof
and most comfortable heart rate transmitter available.
Benefits of Polar transmitter's one piece structure
The Polar transmitter:
Polar Transmission Technology gives you 2500 hours of trouble free use of your transmitter unit, because it is totally service free. Just wash the transmitter occasionally with mild soap water. Due to the unique mechanical structure of the transmitter, the electrodes will not peal off as with some old designs. All this reduces significantly your total cost of using effectively your most important piece of training equipment over time. The cost per hour is about 1.7 cents.
How does the Polar Heart Rate Monitor work?
Polar Heart Rate Monitors measure the electrical frequency of your heart, the number of beats per minute at which your heart is operating. In contrast, pulse meters (photo-reflectance models) use sensors to measure the mechanical pulse of blood flow through your capillaries, which is then converted into a beat-per-minute readout. Polar Heart Rate Monitors are so accurate that readings obtained simultaneously by Polar monitors and by electrocardiogram (ECG) monitors are almost identical. This is not true for photo-reflectance monitors.
