Introduction
Sonoline C1 Pocket Fetal Doppler is a hand-held fetal
heart rate detecting device adopted Doppler theory. It displays fetal heart rate
on digital LCD screen. With easy and convenient operation, it can be used in
hospital and clinic for daily self-check by pregnant woman, realizing early
monitoring and care for life.
Features
