Benefits

The 3M™ Littmann™ Master Cardiology Stethoscope provides the best acoustics Littmann stethoscopes offer, with a significant improvement in low-frequency response. With the unique Master chestpiece, you'll get diagnostic information accurately and efficiently.

• The patented tunable diaphragm alternates between low and high frequencies without turning over the chestpiece. This allows for same-site auscultation.
• Two tubes are incorporated into a single-tube design that eliminates noise artifacts created from two tubes rubbing together.
• Includes a flexible patented special procedures adapter designed for auscultation of difficult body sites (such as ankles, neck, wrists, etc.), pediatric and emaciated patients.
• The headset assembly is permanently set at an anatomically correct angle. This assures a proper fit, minimizes air leaks and prevents the headset from loosening over time.
• Patented 3M™ Littmann™ Snap-tight Soft-sealing Eartips assure maximum comfort and excellent acoustical seal.
• Nonchill rim and diaphragm assembly for patient comfort.
• Seven-year warranty.

Using Your 3M™ Littmann™ Master Cardiology Stethoscope
with patented tunable diaphragm

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.

Bell Mode (low-frequency) Light contact with chestpiece allows you to hear low-frequency sounds.
Diaphragm Mode (high-frequency) Without turning the chestpiece over, use firm pressure to hear high-frequency sounds.
