Radius Tº* is a wearable, wireless sensor that continuously measures a patient’s body temperature. Featuring trending temperature and Bluetooth® connectivity that sends data to remote devices, Radius Tº automates remote continuous assessment of temperature status—allowing care providers to track patient progress and prioritize safety even from afar.

Radius Tº  is designed to help:

  • Streamline Workflows
    Wearability and connectivity capabilities minimize the need for intermittent checks or temperature probes.
  • Inform Care Decisions
    Trended data may provide additional insight into patient status, supporting care decisions and helping clinicians prioritize patient safety.
  • Support Infection Control Efforts
    The ability to monitor from a distance helps clinicians remotely manage patients with a fever or those at high risk of developing a fever.
  • Improve Patient Compliance
    The comfortable, wearable, and water-resistant sensor keeps patients continuously monitored without the need for routine patient action.
