Advanced Acoustic Performance

The Littmann Master Cardiology Stethoscope provides high acoustic performance within the Littmann mechanical stethoscope range. It is designed for physical assessment of heart, lung, and bowel sounds.

The tunable diaphragm allows clinicians to hear different frequency ranges. Light pressure helps emphasize lower-frequency sounds. Increased pressure helps emphasize higher-frequency sounds. This eliminates the need to turn over the chestpiece during an examination.

Dual-Lumen Tubing Technology

The 2161 uses Littmann dual-lumen tubing. Two sound paths are contained within a single outer tube. This design eliminates the rubbing noise associated with traditional double tubing.

The black tubing provides a professional appearance. The 27-inch length also provides convenient reach during routine clinical examinations.
