Easyto operate
CalculatingFHR with the same DSP techniques as used in Fetal Heart monitor, ensure the FHRaccuracy and reliability.
Highsensitive transducer, Low ultrasound power, more safety to the fetus.
Built-inInner speaker.
LCDwith color light or OLED displays the FHR, battery indicator, speaker volumeand fetal heart beating rhythm indication.
AAAdry battery or rechargeable battery acceptable
