- This general-purpose, entry-level stethoscope is an excellent, affordable choice for basic blood-pressure and limited physical assessment.
- Littmann quality is apparent from the soft-sealing eartips down to the combination bell/diaphragm chestpiece.
- The chestpiece is designed for better orientation around blood-pressure cuffs and body contours, and provides clear, reliable acoustic performance.
- Patented 3M Littmann Snap Tight Soft-Sealing Eartips provide an excellent acoustic seal and comfortable fit
- Plus, the tunable diaphragm, for easy low- and high-frequency monitoring, and lightweight design add even more convenience for entry-level stethoscope users
- 28 inches long
- Weight: 118 grams
- Tunable technology provides convenience, versatility and enhanced acoustics. The dual frequency diaphragm combines both bell (low-frequency) and diaphragm (high frequency) into a single side of the chestpiece. You control bell and diaphragm modes by pressure on the chestpiece rather than by turning it over.
- Bell Mode (low-frequency)
- For low-frequency sounds, light contact is used on the chestpiece. The diaphragm membrane is contained by a flexible surround that actually suspends it, allowing the membrane to resonate low-frequency sounds.
- Diaphragm Mode (high-frequency)
For high-frequency sounds, firm contact pressure is used on the chestpiece. By pressing on the chestpiece, the diaphragm membrane moves inward until it reaches an internal ring. The ring simply restricts the diaphragm membrane's movement. It blocks, or attenuates, low-frequency sound and allows you to hear the higher frequency sounds.
No other stethoscope gives you the same quality and efficiency in auscultation. How? Because 3M has the tunable diaphragm technology which allows you to alternate between low and high-frequency sounds without removing the chestpiece.
