Features:
Portable Fetal Doppler mainly applies to detect the fetal heartbeat rate from the twelfth week;

Built-in rechargeable battery can work continuously more than 4 hours;

LCD can clearly display FHR data, hear rate graphics, battery indicator, volume of sound and synchronous FHR signal;

Store and hold FHR data and graphics for up to 12 hours (for option);

Built-in printer with high precision can print synchronous FHR graphics clearly;

Alarm function when FHR is out of the normal range or battery power is in shortage;

Probes with high sensitivity can detect FHR and umbilical blood steam and much easier to interchange;

2.0MHz probe and 5.0MHz probe;

RS-232 port can connect the unit with a computer and store the data by software.
