The Littmann® Master Classic II™ Stethoscope features a tunable diaphragm, which allows the user to conveniently alternate between low- and high-frequency sounds without turning over the chestpiece.  Offers efficiency in stethoscope auscultation that is unprecedented in a general examination stethoscope. The bell and diaphragm modes are incorporated into a single-sided “Master” chestpiece.  No longer will you need to remove the chestpiece from the patient and mechanically switch from bell to diaphragm sides.

Award-winning design combines high performance with portable convenience.
