The SD3 is designed for auscultation (intermittent listening) of fetal sound. The 2 or 3 MHz waterproof probes can be used for the detection of fetal heart rate as a general indication of fetal well being and also to verify fetal heart viability following patient trauma.
The unit can also be equipped with 4MHz or 8 MHz probes for vascular diagnosis.
Features:
- Plug-and-play, waterproof interchangeable probes
- 2 MHz probe with deep penetration for late term-pregnancy and overweight patients
- 3 MHz probe may detect fetal heartbeat as early as 9 weeks
- AA batteries compatible
- Unique charger stand design for organized storage
- Real-time monitoring for daily use
- Bright OLED screen with real-time FHR display
- 4/5/8MHz probe for blood flow detection
