3M™ Littmann® Electronic Stethoscope Model 3100

Hear it. With Confidence. You spoke, we listened. Our Littmann Model 3100 offers improved sound quality and ease-of-use to help you make a clear diagnosis, every time.

Hear What You’ve Been Missing.
The Littmann Model 3100’s exceptional sound quality reduces background noise an average of 85% with our proprietary Ambient Noise Reduction Technology AND amplifies sounds up to 24 times to hear faint sounds you might otherwise miss.

Auscultate Faster.
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.

The Interface You’ve Been Waiting For.
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.

Lightweight, Comfortable and Durable.
The Littmann Model 3100 has been designed to ensure comfort and durability for everyday use, weighing about the same as a cardiology-grade acoustic stethoscope. Comes with two sizes of 3M™ Littmann® Snap Tight Soft-Sealing Eartips for a custom fit and non-chill diaphragm for patient comfort.
