Edan Sonotrax Doppler

A refurbished Edan Sonotrax pocket doppler.

SonoTrax Fetal Doppler provides a simple, easy to use Ultrasonic Doppler that allows mothers and health care professionals to retrieve a fetal heart rate (FHR) and listen to the sound of the heart beat. This Fetal Doppler provides different easy-to-use modes including a Real-time FHR display, Averaged FHR, and a manual mode that allows the user to view a fetal heart rate for a 5 or 10 heart beat period, giving you a calculated measurement with a press of a button.

This Fetal Doppler provides basic features with an LCD screen displaying the FHR, battery indicator, probe type, and different display modes. This waterproof probe provides better ultrasounds of fetal heart beat and allows use in water up to 3 feet for up to 5 hours. The Doppler unit, however, cannot be immerged in water.

The Low Battery indicator provides a full battery icon that indicates full battery levels and decreases slowly after so many uses. A visual and auditory warning will alarm when the battery needs to be changed and then proceeds to automatic shut off.

The 2.0MHz probe was designed to accommodate late term and obese pregnancies since it works best at 10 cm and larger depths.
