Our newly innovation, the all-in-one compact handheld Doppler, SD1, is a remarkable member of our ultrasound Doppler series. Compared with conventional technology, SD1 took a giant leap by introducing the pulse wave technology. The user can locate the fetal heart rate signal quicker and easier.
The extremely low radiation level gives you a safer and more comfortable way during application.
Smart phone solution makes evaluation and examination much more convenient.
In addition, aside with professional clinical usage, SD1 is also an user friendly home-based device that allow you to use it anywhere, everywhere.
