Fetal Doppler

1. The Portable Fetal Doppler is primarily used to detect the fetal heartbeat rate from the twelfth week.

2. The LED can display FHR, and the built-in rechargeable battery can operate continuously for over six hours.

3. The alarm function is activated when the FHR is outside the normal range or when the battery power is insufficient.

4. Automatic power-off (three minutes)5. An earphone jack is located adjacent to the built-in speaker.Specificationinput:
