2Mhz Probe Color LCD Display FD-03 Fetal Dopper Prenatal Heart Monitor
Pocket Fetal Doppler is a hand-held obstetrical unit, which can be used in hospital, clinic and home for daily self-check by pregnant woman.The device uses color LCD of high resolution to display the fetal heartbeat waveform, and figure out the FHR to help the doctor diagnose in time.It contains components of ultrasonic signal transmitter and receiver, analog signals processing unit, FHR calculating unit, LCD display control unit etc.It also has audio output, and can be connected with earphone or recorder with audio input.
Beautiful shape, portable, easy operation
The probe has bending structure which is easy to operate and can increase the ease of the pregnant women, embodies the humane care design
Fetal heart rate values, bar graph and heartbeat waveform color screen display
Alarming in red when the fetal heart rate range is out of the normal range
Battery status indicator
The probe can be changeable
Output for headphone
Auto shut off
Two pieces of standard 1.5V alkaline battery available which can work no less than 8 hours
