The DD-300 is an audio only vascular Doppler. 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.
DD-300 Non-display Digital Vascular Doppler
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.
Superior sound quality
Dopplers have the sensitivity and audio response to allow you to hear the blood flow sounds quickly and clearly. DigiDop Dopplers have 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 DigiDop speakers are small but powerful high fidelity speakers that have extraordinarily smooth and rich response over the whole range of Doppler sounds.
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.
