Feature
1. Portable Fetal Doppler mainly applies to detect the fetal heartbeat rate from the twelfth week.
2. Built-in rechargeable battery can work continuously more than 4 hours.
3. 3.2'' Color LCD can clearly display FHR data, hear rate graphics, battery indicator, volume of sound and synchronous FHR signal.
4. Store and hold FHR data and graphics for up to 12 hours (for option).
5. Built-in printer with high precision can print synchronous FHR graphics clearly.
6. Alarm function when FHR is out of the normal range or battery power is in shortage.
7. Probes with high sensitivity can detect FHR and umbilical blood steam and much easier to interchange.
8. 2.0MHz probe(1.0MHz probe and 5.0MHz for option).
9. RS-232 port can connect the unit with a computer and store the data.
10. Software is option.
