Littmann Classic III Monitoring Stethoscope, 5811

Two-sided chestpiece with tunable diaphragms on both the adult and pediatric sides
Single-piece tunable diaphragm is easy to attach, and easier to clean because its surface is smooth without crevices
Pediatric side converts to a traditional open bell by replacing the single-piece diaphragm with a non-chill rim
Next-generation tubing provides longer life due to improved resistance to skin oils and alcohol; less likely to pick up stains. Chestpiece Weight: 2.9 Ounce
