Stethoscope offering high acoustic sensitivity for exceptional performance, plus a versatile 2-sided chestpiece with tunable diaphragms. Used to identify, listen to and study heart, lung and other body sounds for physical assessment, patient monitoring and diagnosis. Tunable diaphragm technology lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Time-saving feature allows healthcare provider to focus on patient by holding the chestpiece with light pressure to hear low-frequency sounds and press a little more to hear higher-frequency sounds. 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.
