Its unique computer-designed chestpiece allows you to modulate between low and high frequency sounds by simply alternating pressure on the chestpiece.
Unique patented chestpiece
The traditional bell and diaphragm modes are incorporated into the single-sided "Master" chestpiece. To hear low frequency sounds typically heard with a traditional bell side of a chestpiece, simply use light contact on the skin. To hear high frequency sounds typically heard with a diaphragm side, apply firm pressure.
No longer will you need to remove the chestpiece from the patient and mechanically switch from a bell side to diaphragm side. You can switch from low to high frequency response instantly without interruption.
The new "Master" chestpiece makes it easier to auscultate under a patient's gown. You'll never have to check which mode you're in or tap on the diaphragm.
Compared to the traditional two-sided Littmann Classic II stethoscope, the high frequency response of the Littmann Master Classic II stethoscope is outstanding, allowing you to hear even faint lung sounds. The low frequency response is also significantly improved.
Its excellent overall acoustics offer an advantage to heath care professionals who listen to both heart and lung sounds. It's also ideal for pulmonologists and respiratory therapists.
