3M Littmann Master Cardiology Stethoscope (Black)

The 3M™ Littmann® Master Cardiology™ Stethoscope features tunable diaphragm technology—a 3M invention—that lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Unlike two sided models, there’s no need to turn over and reposition the chestpiece. Hold the chestpiece 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 rim provides patient comfort. Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. Snap tight, soft sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove.
