The EKG Receiver is a new sensor designed by Thought Technology. It detects the heart rate of a user from the Polar™ transmitter belt that the user wears around the chest.

Polar™ transmitter belt is not provided by Thought Technology and must be purchased separately. It can be easily purchased at your local major department stores, sports specialty stores, and other stores.

Supported Encoders

FlexComp Infiniti, ProComp Infiniti, ProComp5 and ProComp2.

Wireless Range

The wireless reception range of the EKG receiver is deliberately kept short, typically 80cm (2.5 feet) to prevent it from connecting with other belts in the immediate vicinity of the user.

Coded or not coded?

Polar has 2 variations of transmitter belts: coded and non-coded. Polar CODED Wireless Technology is to greatly reduce CROSSTALK issues when equipment is placed in close proximity to other equipment (typically in health clubs where equipment is placed <1 ½ feet apart.), so that one person’s Polar watch won’t pick up the heart rate from the person next to you.

Our Polar EKG Receiver can detect heart beats from both coded and non-coded Polar transmitter belts. However, it does not differentiate between them. It will receive and process the signal and treat the coded belt as a NON-CODED one.

Compatibility with Polar™ products

The EKG Receiver is compatible with Polar™ T31 transmitter, Polar™ T31c (coded™) transmitter and Polar™ WearLink®+ transmitter.
