A streamlined heart rate sensor with soft textile strap that connects to Polar heart rate monitors using 5 kHz transmission.
Comfort is the key when training. That’s why Polar created the slim H1 heart rate sensor. It not only measures your heart rate but also seamlessly adapts to your body shape, so you can forget you are wearing it and focus on your exercise. It’s even easier to put on than a pair of trainers!
Compatible with: FT1, FT2, FT4, FT7, FT40, FT60, FT80, RCX5, RS400, RS300X, RS100, CS300, CS200cad, CS100.
