The SD3 Ultrasonic Pocket Doppler offers superior performance for a great value. With excellent sensitivity, complete interchangeability, and high durability, the SD3 series Ultrasonic Pocket Dopplers is ideal for routine fetal heart rate detection.

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

The Edan SD3 Ultrasonic Pocket Doppler is a high-performance, compact device designed for reliable fetal heart rate detection in obstetric and maternity settings. Featuring easy one-hand operation, a bright OLED display for real-time fetal heart rate (FHR) visualization, and plug-and-play waterproof interchangeable probes, it's ideal for routine fetal monitoring and verification of fetal viability. With options for a 2 MHz probe (for deeper penetration in later-term or larger patients) or a 3 MHz probe (capable of detecting fetal heartbeat as early as 9 weeks) and AA-battery power compatibility, the SD3 offers both flexibility and portability. Additional models (Plus, Pro) offer enhanced features such as rechargeable lithium-ion batteries, audio recording of fetal heart sounds, and automatic power-off when the probe is returned to its rack.

Key Features:

• Real-time OLED display showing fetal heart rate.

• Interchangeable waterproof probes: 2 MHz (deep penetration), 3 MHz (early detection from ~9 weeks)

• Compact “pocket” design suitable for one-hand operation.

• Battery power: standard AA batteries (in base model) or rechargeable options in higher models.

• Durable build, good value for routine clinical use.

Applications:
Used in obstetrics and prenatal care to monitor fetal heart sounds (auscultation), confirm fetal well-being, check fetal viability following trauma, and for routine check-ups. The SD3 is suitable for use in L&D, antenatal clinics, OB offices, and mobile/portable settings.
