EDAN SD1 Ultrasonic Pocket Doppler with Bluetooth

The EDAN SD1 is an all-in-one compact handheld fetal Doppler that represents a significant advancement in portable fetal heart rate monitoring. By introducing pulse wave technology, the SD1 surpasses the limitations of conventional Doppler devices—users can locate the fetal heart rate signal more quickly and easily, with less dependence on probe angle and fetal heart depth.

Designed for both professional clinical use and home-based fetal monitoring, the SD1 features an exceptionally low radiation level for safer and more comfortable application. The Bluetooth-enabled model (SD1-B) connects wirelessly to a smartphone app, allowing users to view and save real-time fetal heart rate values and curves. Whether you are an obstetrician, midwife, or an expectant parent, the SD1 offers a convenient and reliable solution for fetal heart rate monitoring anytime, anywhere.

FDA 510(k) cleared for detecting fetal heartbeats from the 10th week of gestation.
