Our new fetal Doppler is designed to listen to your baby's heartbeat while it is still in the womb. It uses safe ultrasound technology to send high-frequency sound waves into your abdomen. When the sound waves encounter movement, such as your baby's heartbeat, it sends a signal back to the device through the handheld probe. The signal is then translated into a sound which is then amplified, so you can hear it.

FEATURES AND BENEFITS:

• It is a hand-held obstetrical unit. They use a standard 2XAA 1.5 V alkaline battery.

• It contains components of an ultrasonic signal transmitter and receiver, analog signals processing unit, FHR calculating unit, LCD control unit, etc.

• It is a high-performance model with a (fetal heart rate) LCD digital display. 

• It features 3 modes, including real-time FHR display mode, averaged FHR display mode, and manual mode.

• It has audio output and can be connected to an earphone or recorder with audio input. 

• Highly sensitive probe is more accurate: High-sensitivity wide-beam 2.5MHz probe ensures reliable measurement throughout pregnancy.

• Intelligent noise reduction heart sound is clearer: The use of digital filter noise reduction technology can greatly reduce the noise of the instrument and the output is clearer.

• The autocorrelation algorithm is accurate and reliable in measurement: The autocorrelation algorithm can effectively eliminate the interference caused by the external environment, suppress the noise in the echo signal, improve the accuracy, reduce the amount of calculation, increase the response speed, and ensure the accuracy of the measurement results.
