The new Classic III stethoscope offers you:

  • High acoustic sensitivity when performing general physical assessment.
  • Tunable diaphragms on both the adult and paediatric sides of the chestpiece.
  • Tunable technology is a 3M invention that lets you shift between hearing high and low frequency sounds by simply adjusting how much you press on the chestpiece.
  • Single-piece diaphragm that’s easy to attach and easy to clean because the surface is smooth and without crevices.
  • Soft-sealing eartips give you a comfortable fit and an excellent acoustic seal; they snap tightly onto the eartubes for safety.
  • Open bell versatility allows the paediatric side to convert to a traditional open bell by replacing the single-piece diaphragm with a non-chill sleeve.
  • Next-generation tubing with improved resistance to skin oils and alcohol for longer tubing life. Less likely to pick up stains.
  • Chestpiece is precision-machined into an aesthetically pleasing, less angular shape. The stem features an open side indicator.
  • Classic III stethoscope includes a 5 year warranty.
