BRAND NEW! Never taken out of box. Extra pieces included The Classic III stethoscope brings new design, materials, and technology to the Littmann stethoscope series that’s been used and trusted by millions of medical professionals worldwide for decades. With a two-sided chestpiece, dual tunable diaphragms, improved tubing, and much more, the Classic III stethoscope combines the best of new and traditional. Full adult and pediatric auscultation is available through its dual head chestpiece simply by rotating the central spline to alternate between the two sides. The more compact one piece diaphragm and rim assemblies have further increased acoustic sensitivity. The binaurals have been redesigned with larger diameter ear tubes and a thicker single lumen binaural to transfer sound more effectively. The selector spline is now recessed to allow a flush fit with the binaural tube and now features a visual indicator for easy identification of the operational diaphragm.
