Our mini telemetry system offers:

  • Freedom
    • Mom won’t be tied to bed, so she can move around more naturally, improving the birthing experience.
  • Flexibility
    • Moms can walk around and use the lavatory while still being monitored, allowing moms to comfortably engage in more activities and different types of birthing options.
  • A laboring in water option
    • The waterproof Nautilus Transducers allow moms to take advantage of the soothing benefits of aquatherapy. 
  • Improved safety
    • The small, light transmitter is easy to carry, and a recess in the unit improves safety through cable management.     


Some of the technology that makes GE’s mini telemetry system an exceptional choice is:

    • Mini Telemetry uses proven Nautilus waterproof 9-crystal ultrasound transducers, which are identical to those used with all Corometrics/GE fetal monitoring products.
  • Wireless technology
    • The wireless telemetry technology offers exceptional signal quality, letting mom ambulate during labor.
  • Compact, 3-port design
    • The compact, 3-port design allows FHR, uterine activity, and ECG monitoring and allows you to monitor twins as well.
  • Longer battery life
    • An extended-life battery accommodates the full duration of the average labor (up to 12 hours) with a built-in charging bay.
  • Mobile monitoring technology
    • Speakers or a headphone jack are built into the unit, offering audio monitoring of fetal heart rate while mom is mobile. 
  • User-friendly features
