Brief Description
●  Easy to operate
●  LCD with color light or OLED displays the FHR,battery indicator,speaker volume and fetal heart beating
      rhythm indication.
●  High sensitive transducer, Low ultrasound power, more safety to the fetus.
●  Built-in Inner speaker.
●  AA dry battery or rechargeable battery acceptable
●  Accurate FHR and the same advanced FHR algorithm with that used in fetal monitor
●  Automatic power-off when no signal or no operation
