Rechargeable Digital Vascular Doppler without Display

These audio only Dopplers provide great value if all you need is to hear the Doppler sounds loud and clear. They include a display of battery condition, signal strength, and volume setting, but do not have a heart-rate display.

The DD-330R is an audio-only vascular Doppler with a recharger. The display indicates battery, volume, and signal strength status - DOES NOT display pulse rate. The powerful digital processor in the DigiDop utilizes Digital Signal Clarity - DSC to eliminate background noise and amplify a strong clear signal.

Superior sound quality

Our Dopplers have the sensitivity and audio response to allow you to hear the blood flow sounds quickly and clearly. All our DigiDops have our state of the art Digital Sound Clarity – DSC™. A sound processor in the main unit enhances the sounds you want to hear while reducing those you don’t. The DSC™ processing is optimally set for each different probe frequency.

The DigiDops speakers are small but powerful high fidelity speakers that have an extraordinarily smooth and rich response over the whole range of Doppler sounds.

All DigiDop vascular probes provide the sensitivity and reliability you need. All probes will work on all DigiDops for maximum versatility.   Our 5 and 8 MHz vascular probes have a smooth contour design that is comfortable to hold, comfortable for the patient, and easy to clean.

  • 5 MHz probes provide excellent deep penetration for deeper arteries and for deep veins
  • 8 MHz probes are especially sensitive for vessels near the surface like the radial, posterior tibial, and dorsalis pedis arteries.
  • Audio PPG probe. The DigiDop family of vascular probes also includes a unique PPG probe that generates audible sounds with each pulse. It is an excellent addition for obtaining pulses in the digits to assist in toe-brachial index or penile index measurements.
  • A variety of obstetrical probes can interchangeably by used with any of the DigiDops.
