From the Manufacturer

The 3M Littmann Master Classic II Stethoscope features tunable diaphragm technology that offers reliable, versatile acoustic performance and the portable convenience of a single-sided chestpiece.


Tunable Diaphragm - the Heart of the Master Classic II Stethoscope

This stethoscope is used by students and medical professionals alike to detect, listen to, and study heart, lung, and other body sounds for physical assessment and diagnosis. 3M Littmann tunable diaphragm technology delivers excellent 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 longer a need to remove, index and replace for same-site auscultation. 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 Master Classic II is made in the USA. The product and package are latex-free and come with an alternate pair of small eartips and instructions.

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.
