3M Steth-Master Cardio #2160

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 the 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.
