The Littmann Model 3100’s exceptional sound quality reduces background noise an average of 85% with it’s proprietary Ambient Noise Reduction Technology and amplifies sounds up to 24 times to hear faint sounds you might otherwise miss. You can auscultate immediately, thanks to our instant-on technology. The Littmann Model 3100 is easy to use for quick auscultation every time. Once on: power button quickly activates backlight for low-light conditions
and the stethoscope stays in battery-saving “sleep mode” until you start your next auscultation. Incredibly simple and non-disruptive to your auscultation workflow.
The easy-to-read backlit LCD display includes frequency selection, sound level, remaining battery life and your
patient’s heart rate.
