3M Littmann Classic III Black Stethoscope

The 3M™ Littmann® Classic III S.E. Stethoscope provides high acoustic sensitivity through its dual-sided, stainless steel chestpiece, featuring a tunable diaphragm on one side and a traditional bell function on the opposite side.

Tunable diaphragm captures high and low freq. sounds

Place diaphragm on surface to listen in bell mode

Apply slight pressure to listen in diaphragm mode

Resilient tubing folds easily for pocket portability

Tunable Diaphragm – the Heart of the Classic III S.E. Stethoscope
3M™ Littmann® tunable diaphragm technology and dual sided chestpiece deliver high acoustic sensitivity, versatility, and time-saving convenience. Switching between bell and diaphragm modes is as easy as a simple pressure change on the chestpiece, which means there is no need to remove, index and replace for same-site auscultation. The resilient tubing folds tightly for pocket portability and retains its shape while patented Snap Tight Soft-Sealing Eartips help form an effective acoustic seal. The anatomically correct headset is angled to channel sound and enhance listening comfort while the nonchill rim and diaphragm provide patient comfort. The Classic III SE is made in the USA. The product and package are latex-free and come with an alternate pair of small eartips and instructions. The Classic III S.E. is used by students and medical professionals alike to identify, listen to, and study heart, lung, and other body sounds for physical assessment and diagnosis.

What is a Stethoscope?
Stethoscopes are diagnostic instruments that amplify sounds made by the body from the heart, lungs, abdomen and intestinal tract, or other body sites. A stethoscope is used to detect and study internal systems, such as fetal development, blood flow or blood pressure (BP), and respiration, and sounds, such as cardiac, venous, arterial, pulmonary, and uterine. Stethoscopes typically have Y-shaped rubber tubing that allows sound to travel from the chestpiece to the eartips. An open bell detects low frequency sounds, and a diaphragm detects high frequency sounds. A stethoscope can come as single, double (dual), or triple-head. Binaural stethoscopes are used with both ears, and single stethoscopes work with one ear. Differential stethoscopes are double-head, and allow sound comparison between different body sites. Non-electronic, also called mechanical or acoustic stethoscopes, transmit sound through hollow tubing to a listener’s ear. Stethoscopes are used by students and a wide array of healthcare providers including physicians, nurses, and veterinarians, as well as specialists such as cardiologists, pediatricians, gastroenterologists, pulmonologists, and respiratory professionals in hospital, clinical, or other healthcare facilities.
