The 3M™ Littmann® Master Classic II™ Teaching Stethoscope allows instructors and students to simultaneously auscultate patients with excellent acoustic sensitivity. This stethoscope combines the reliable, versatile acoustic performance of tunable diaphragm technology with the portable convenience of a single-sided chest piece. The Master Classic II 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.
Tunable diaphragm technology—a 3M invention—lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Unlike two-sided models, there’s no need to turn over and reposition the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time-saving feature allows the healthcare provider to focus on the patient, while the non-chill rim provides patient comfort.
