The 3M™ Littmann® Master Cardiology™ stethoscope is characterized by the best acoustic response in the Littmann® mechanical stethoscope line; with a tunable diaphragm, dual-lumen tubing, and a precision, ergonomically designed, stainless steel chestpiece. The 3M™ Littmann® Master Cardiology™ stethoscope features tunable diaphragm technology - a 3M invention - that 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.
