3M Littmann Master Cardiology Stethoscope, Black With Smoke Chest Piece And Binaurals

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 chest-piece. Unlike two-sided models, there is no need to turn over and reposition the chest-piece. 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 rim provides patient comfort.Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the ear-tubes. Snap-tight, soft-sealing ear-tips conform to individual ears for an excellent acoustic seal and comfortable fit. Ear-tips snap firmly onto the ends of the ear-tubes and, for safety, require a significant effort to remove. It is black in color.
