Polar™ EKG Receiver (SA9330)

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


Important Notes

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

Also note that this belt is sold as a consumer device, and may not be designed and manufactured to meet the safety and biocompatibility standards required for a medical device. The customer/clinician is responsible for ensuring that the belt is appropriate for use with their clients.

Technical Considerations


The Polar EKG Receiver works with any channel set in BioGraph that has either a BVP or an EKG sensor. For optimal performance, the use of the BVP algorithm is recommended, especially when the Heart Rate is higher than 140 beats/min.

Supported Encoders:

FlexComp Infiniti, ProComp Infiniti, ProComp5 Infiniti, ProComp2 and ProComp+.

Wireless Range:

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

Coded or Non-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 <1½ 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.

T31 Coded™ Transmitter

At the heart of your training is the coded T31. Its purpose is simple: to transmit your heart rate to your wrist unit. Slim and light, the ECG (electrocardiogram) accurate transmitter is fully water resistant and designed for all weather conditions.

Compatibility with Infiniti: the EKG Receiver will receive and process the signal but will treat it as a NON-CODED belt (like a T31 transmitter)

T31 Transmitter

Slightly different to the T31c Transmitter, the slim, light and waterproof T31 doesn't have the benefit of coding for interference free transmission. However, its purpose remains the same: to transmit your heart rate to your wrist unit ECG (electrocardiogram) accurately.

Compatibility with Infiniti: fully compatible.

WearLink®+ transmitter
WearLink®+ Transmitter W.I.N.D.

Compatibility with Infiniti: NOT compatible.
