The 3M™ Littmann® Lightweight II S.E. Stethoscope is an ideal entry level instrument, with a tunable diaphragm, dual-sided chest piece, and reliable acoustic performance. Its teardrop shape makes auscultation around blood pressure cuffs easier. It provides reliable acoustic performance for taking blood pressure readings and making limited physical assessments of adult patients. Hold the chest piece 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 diaphragm and rim provide patient comfort.
