The Edan SD3-Plus.04 Handheld Vascular Doppler offers precise acoustic clarity for deep peripheral blood flow evaluations. Outfitted with a bright, high-contrast OLED display screen and a built-in speaker assembly, this lightweight diagnostic system tracks hemodynamic velocities while filtering out underlying tissue artifacts. The included 4 MHz waterproof transducer probe provides optimized lower-frequency wave depth, protecting monitoring accuracy and allowing medical teams to reliably locate and examine deep-seated arterial and venous vessels.
