The 3M Littmann Classic III Monitoring Stethoscope offers high acoustic sensitivity for exceptional performance, plus a versatile two-sided chestpiece with tunable diaphragms on both the adult and pediatric sides. This stethoscope is used by students and medical professionals for non-critical care physical assessment, patient monitoring, and diagnosis. Tunable diaphragm technology lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. This time saving feature allows the healthcare provider to focus on the patient, while the non chill rim provides patient comfort. Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. Snap tight, soft sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Resilient next generation tubing retains its shape and flexibility even after folding tightly into a pocket. It provides longer stethoscope life due to improved resistance to skin oils and alcohol, and is less likely to pick up stains. Length: 27.2".
