Superior versatility and outstanding acoustics. The 3M Littmann Cardiology III Stethoscope is the very latest innovation in auscultation technology. The large side can be used for auscultating adult patients, while the small side is especially useful with pediatric or thin patients. Two patented tunable diaphragms allow for listening to both low and high-frequency sounds with either side of the chestpiece. Two tubes are incorporated into a single-tube design that eliminates noise artifacts created from two tubes rubbing together. For long lasting performance and proper fit, the headset assembly is permanently set at an anatomically correct angle. This minimizes air leaks and prevents the headset from loosening over time. To provide your patients with extra comfort, each chestpiece side features a nonchill rim and diaphragm assembly. Patented 3M Littmann Snap-tight Soft-sealing Eartips assure maximum comfort and excellent acoustic seal. An extra pair of small soft-sealing and firm eartips are provided to assure a personal fit. Note: tubing is measured from the top of the eartips to the bottom of the chestpiece. Five-year warranty. Use Tunable technology provides convenience, versatility and enhanced acoustics. Its dual-frequency diaphragm combines both bell (low-frequency) and diaphragm (high-frequency) modes in one chestpiece side. You control bell and diaphragm modes by pressure on the chestpiece rather than turning it over. Featured is both an adult and pediatric-sided chestpiece, each incorporated with a tunable diaphragm.
