Safe way to hear your baby’s heartbeat in the womb, from only 12 weeks in the comfort of your own home.
The Sonoline B displays the fetal heart rate (FHR) on a backlit digital LCD screen and also has a built in loudspeaker to listen to the heart rate.
The fetal doppler emits and receives totally safe small high frequency sounds waves (ultrasound) which reflect off the fetal heart. Based on the Doppler Effect principles the device uses the differences in frequency and wavelength between the emitted and received waves to calculate the fetal heart rate (FHR).
