Littmann Stethoscopes are the name you know & trust when it comes to getting outstanding acoustic performance combined with exceptional versatility. The Littman Cardiology III series has an innovative design that offers a proprietary tunable diaphrahm on each side of the chest piece.
What users of the Littmann Cardiology III love about it is the double sided chestpiece which makes it work for either adult or pediatric auscultation. While the pediatric side can even be converted to an open bell for low frequencies using a non-chill bell sleeve (which is included!).
The new two-in-one tube design (dual lumen) eliminates tube rubbing noise from the two tubes rubbing together.
Specifically, when referring to the Breast Cancer Awareness stethoscope above, 3M/Littmann will contribute $5 to the American Cancer Society to help support Breast Cancer Awareness.
