The SA9330 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.

The EKG Receiver is compatible with Polar™ T31 transmitter and Polar™ T31c (coded™) transmitter (but code feature is not supported).

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.

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 and Polar™ T31c (coded™) transmitter (but code feature is not supported).

  • Wireless transmission from the transmitter to the EKG receiver, thus no electrodes are needed.
  • Heart beat signal is less prone to movement or EMG artifacts, and is very stable, so you have freedom of movement.
  • Polar™ transmitter belts are slim and light, easy to position on the chest, fully water resistant, and are designed for all weather conditions.

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.
