2.4 Inch TFT Display Medical Grade Pocket Fetal Heartbeat Doppler 300HZ

 

 

Fetal doppler is handheld diagnostic instrument. It is used to test fetal heart rate in obstetrics department and clinics. It is made up of ultrasound signals transmitter and receiver, analog signal processing,calculation of fetal heart rate and liquid crystal display.

 

1. Color 2.4 inch TFT display, the font and screen colour can be adjusted.

2. Calculating FHR with the same DSP techniques as used in Fetal Heart Monitor, and ensure the FHR accuracy and reliability.

3. High sensitive transducer, the transducer is 2.0MHZ with continuous wave work mode, Low ultrasound power, safe to the fetal.

4. Friendly man-machine interface, easy to use.

5. Built-in speaker and ear-phone output.

6. 7.4V lithium battery and battery status indicator.

7. Battery fuction: Under the normal working mode, auto power off if there is no signal more than 20 second.
