Littmann Cardiology IV Features and Benefits
The Littmann Cardiology IV Stethoscope is a leading cardiology stethoscope for clinicians who need superior acoustic sensitivity, durability, and diagnostic versatility in demanding environments.
Outstanding acoustics with improved audibility of high-frequency sounds when firm pressure is applied on the adult side.
Dual-sided chestpiece with tunable diaphragms on both sides supports adult and pediatric patients, and the pediatric side converts to an open bell.
Tunable diaphragms let you hear high or low frequency sounds by adjusting pressure on the chestpiece.
Two sound paths in one tube eliminate the rubbing noise associated with traditional double tubes.
Adjustable headset and angled eartubes align with ear canals for individual fit and comfort.
Personalize your stethoscope for identification, gifting, or professional presentation.
