Polar T31 Heart Rate Sensor (Non-Coded)
The non-coded T31 heart transmitter kit from Polar is lightweight, water-resistant, and slimcut. The transmitter belt comes with a medium strap designed to fit chest sizes from 25” to 54”. While it doesn’t have the interference-free feature of the Coded T31C model, this unit is still highly dependable for accurately transmitting your heart rate to your wrist unit ECG.
The Polar T31 is GymLink compatible and works with most Polar-compatible equipment and older non-coded Polar heart rate monitors. The battery is not user replaceable, but the lack of a battery compartment helps reduce the risk of leaking or failure, and the battery life itself can extend to 5-6 years based on 1-hour daily use.
The easy-to-set-up T31 kit is compatible with GymLink and most Polar-compatible monitors and gym equipment. *Please Note: This sensor cannot function as a stand-alone unit, it must be paired with a compatible device that receives transmissions from this sensor
