T31C Heart Rate Sensor by Polar - on a white background

T31C Heart Rate Sensor

$56.00 CAD

T31C Heart Rate Sensor (Coded)

This version of Polar’s T31 heart transmitter kit is coded, which means it’s designed with a special feature to prevent interference or crosstalk from other nearby electronic devices (a Non-Coded version of the T31 is also available for those unconcerned with potential interference in their training space). The overall unit is uniquely lightweight, slim, and water-resistant, with an elastic strap sized for 25” to 54” chests.

The T31 is a proven device for accurately and consistently transmitting heart rate data to a wrist unit ECG. Whether training in the gym or running or swimming outdoors, a clear, reliable readout makes all the difference. The battery (not user replaceable) is also built to last, with up to 2,500 hours of training usage.

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

T31C Heart Rate Sensor is rated 3.6 out of 5 by 5.
Rated 1 out of 5 by from Does't play well with echo bike Purchased a month ago to use with new echo bike. I've found the worst feeling in the world is doing a heart rate workout putting out max effort for several minutes and the heart rate monitor is telling you 100 bpm. Or it will tell you the accurate number (170/180 bpm) and as your intensity increases the bpm will decrease. It completely ruins the workout because you just end up burning yourself out attempting to raise it to where it should be. And after minutes of this when you are completely smoked, frustrated, fed up, and stop pedaling cursing the machine it will shoot up to 180/190 bpm where you know your heart rate is and has been. Very frustrated. Read the manual and trouble shooting. Better off without the frustration.

Rated 5 out of 5 by from SYNCHS WITH MACHINES AT THE GYM! I need a HR monitor that talks to the machines at the gym I go to. This is it! Most of the new HR monitors do not communicate with anything other than their own products, but this one talks to everything at my gym. It even talks to an old Polar wrist band that I have had for 10 years. It's exactly what I needed!
